Why don't you try holding Option during the chime to see if it shows up before creating threads about it? Then, if it doesn't work, search, and if you don't find an answer -- ask the question.
This all stemmed from your Windows 10 thread.
Not trying to be aggressive -- we just don't need a thread for every simple question you've already asked in other threads.
OpenCore has "settings" that will allow you to boot with the apple logo, and bypass the picker, , it sound like this option in the settings was chosen.
As to weather the card was flashed, possible , did you buy it used ?
i have two saffire pulse 580/570, both bought used off ebay, with no incling of being flashed, but they both show apple logo upon booting plain mojave, no opencore. i dont have an answer either, but i wont look a gift horse in the mouth....carry on...
That Apple logo only shows AFTER the GPU driver is loaded. Therefore, when you see it, the loading bar is already there, and most likely is already half loaded.
When we talking about the boot screen. It's the screen that BEFORE GPU driver is loaded.
e.g. Boot picker, it works even before any OS started to load.
If you have a working boot screen, when you boot macOS, you should able to see the Apple logo before the loading bar appear.
That's why I said it's not the boot screen, but when you can see the Apple logo, the GPU driver is already loaded. And that's why the loading bar is already there.
It's very simply, if you have a real working boot screen. You can hold Option key to boot, then select Mojave at the startup disk manager.
But if you don't have the real boot screen, holding option key to boot will make your cMP hang with black screen.
Since you don't have OpenCore installed, therefore, we don't need to consider OpenCore's boot screen effect.

I"m sorry if I rehashed a repeat on another post.
I'm stuck. Downloaded OCLP patcher 1.2.1. Clean install of High Sierra, then Download OpenCore. Everything goes smooth as expected through the process, EFI build and all. Until I'm asked to reboot and hold down the (option) key I hear the chime and held down the option key for over 30 minutes and nothing, done three times and no boot?
Please help. I followed this process step by step from Mr. McIntosh and it's great step by step.
I'm using a NVMe PCI drive. Maybe that's why ?
I never had no problem before when using Martion Lo's process seeing the boot picker.
I wanted to try OCLP as another alternative, but not getting a boot screen, any help would be greatly appreciated.

according to oclp site, any oclp version 1.0.1 or above wont boot below big sur..it happened to me, wouldn't let me boot mojave, i got the đźš« symbol.
i suspect if you want high sierra you would have to remove the oclp drive..
Update. Okay as I mentioned I tried for days to install Opencore while holding down the (OPTION) never got a boot screen.
I could not imagine with just building the USB installer and with nothing in the computer except the USB OC installer, pressing (P+R+option+Command), chime twice then let the USB OC installer boot.
Then shut down and then install an empty SSD, turn on the computer and I got the boot screen, and installed Monterey.
In case someone is not getting a boot screen on holding down the Option key when rebooting.
Thank you all.
The only problem I'm trying to figure out is my Wi-Fi is trying to auto connect to my router but not happening. It was a padlock I can't unlock?
This is the video that worked great.

well, thats a new way to do it, but like you said holding option on boot does nothing for me, until one day i had the usb installer in and just let it go to boot picker and to my surprise i could see the installer in the boot screen. i clicked on it, it went thru its process and finally installed sonoma...so theres a few different ways to accomplish the task
I think after you have installed OpenCore, the key you need to press to get to the OC bootscreen is Spacebar.
