I do believe there is a terminal command that can do that, but it also does some wonky stuff at times.

Neither of these work on my new 2.3GHz i9 16". Are there any command updates I can try? The auto boot, in particular, is bothersome.
iFix it has a guide for that. Give it a try...

Unfortunately, the iFixit guide offers the same Terminal commands as above. They don't work with Catalina, apparently. I gave it a try ... thanks for playing!
The autoboot command works correctly on my 16" MBP. To disable you need "sudo nvram AutoBoot=%00".
Yes, but with a cavaet: Now pressing any key boots the machine. I can live with that much more easily than I could handle auto-boot.
That's not a caveat, that's the normal design. Even with auto boot on, it still boots with any key on (for example if you shut it down with the lid open, pressing any key turns it on again).
I actually miss the chime. Thankfully my PowerBook G4 still has one. Just keep it around for email and browsing 'the old net' website for a taste of nostalgia.
I noticed it when I first booted my new MacBook Pro 2019 after my 2012 model died. I thought it was odd that it didn't play one. I suppose I've grown accustomed to hearing it when waking it up or turning it on the first time.
I think this is why Apple got rid of it. The chime is heard so little anyway as most people simply sleep their Mac rather than shutting it down.

Still, sad to see such an iconic part of the Mac disappear.
My 2012 would 'hibernate' (sleep itself just drained the battery) when I closed the lid (had it configured that way) and it always woke up with the chime even though it wasn't actually rebooting.
At least my PowerBook G4 still chimes. I don't get used to changes like that much. I tend to notice even the tiniest thing being different. The lack of chime on my new Pro made me wonder if the speakers worked or I needed AirPods to use the sound.
My first Mac experiences were with a Classic someone gave me in the late 1990s, it beeped rather than chimed. I also had a collection (that I still kick myself over selling) of 1990s-2000s era Macs including a pre-iMac all-in-one G3. I actually adjusted to OS X a little difficult since I grew used to OS 7-9. I was used to seeing a 'happy Mac' every startup not a huge banner saying 'Mac OS X'. The 'Happy Mac' was like the chime--an indication, however subtle, that the Mac was booting normally.
