split fusion drive

Do you have a backup of all your data? Everything will have to be deleted to rejoin them.
When you are ready, create a bootable macOS installer, or boot from Internet Recovery. In Disk Utility, you should see the drive in red, with a message asking if you want to join them again. If that's not the case, open the Terminal.
The syntax is then thus
diskutil coreStorage create nameYourThing drive1 drive2
nameYourThing obviously is whatever you want it to be called, and drive1 and drive2 respectively are the disk identifiers for the SSD and HDD

Problem may be if you opted to format the blade drive as APFS. APFS will not run on a Fusion so perhpas reformat the Blade back to HFS+ and do a re-install after backing up.
Questions:
How is the iMac running right now?
Good and smooth?
Fast?
No other problems?
If so, I'd just "let it be".
The SSD portion of the fusion drive will always "run at its best" as a "standalone" SSD.
"Fuse" it back with the HDD, and it may begin to slow down on you.
