Updating to big sur?

Updating to big sur?

First post here but could do with a lil help... (sorry it's long winded)

So I've had hackintosh running on my pc for a few months now on catalina and recently I heard of the release of big sur and jumped right onto my computer to install it but only got errors. Today I thought I'd try again at this and see if I could do this some other way and instead I discovered the problem was not me (for once) and taht my computer was showing as as a late 2014 imac which I found out was not actually compatible with big sur and I was just wondering if there's a way to change what model of mac it's pretending to be?

Thank you all

TL:DR How do I change what mac my pc is pretending to be?

(Also my parts if you're wondering)
