I don’t understand fusion drives. Can someone please tell me?

Hi! So I’m looking to upgrade my iMacs Fusion Drive to a ssd, but I want to take the Fusion Drive out so it is just the data ssd. How do I remove the ssd part of the Fusion Drive? Or is the ssd but if the Fusion Drive in the main drive or is the ssd on the main board? I am getting mixed results from asking.

iMac 27″, macOS 15.0

That 2013 iMac has a 3.5" HDD that can be replaced with a 2.5" SATA SSD using a tray and cable kit.

If it is Fusion drive model, then it has a non-standard SSD on the backside of the logic board.

Considering the 2013 iMac's age and limited ability to run anything later than macOS 10.15 Catalina.

It would be best to just run it from an external SSD and save up money for a new Mac.
