Hello Pehem17260,
did you come into the Installer und do get stuck before the Hackintosh can boot into the Installer?
I used this modified cpu-patch whre you can boot into BigSur Beta 1 and 4 (others I don't have), what
is attached as 15h_16h.plist .
For your config.plist use the setting what are documendated in:
Then start with changes, if needed.
You will come in the Installer (see Screenshot), but in my hardware combination it crashes after 2 Minutes.

It crashes so fast, that it is hard to make a foto with the Mobile camera, but see the Screenshot in Combo with
AMD FX 6300 and GT710:

I'm not a Guru like Shaneee, but I think (that means I don't know it for sure!!!!!!!!!!!!!!!) it can be that the hardware
combination causes the crash or the uncomplete cpu-patch, where the Limit goes up to the Catalina 10.15.6 Beta 6.
I other guy i know, could start and complete the Installation, but with a AMD RX 560.
On the other Hand he can not boot with the GT710, not even in the Installer or in the installed Big Sur.
But for some unknown reason he does not want to share or compare our config.plist, Kexts and Drivers.
And that's what I don't understand, because only when we share Infos about our config.plist, Kexts and Drivers,
we can get success with Big Sur.
Oh, I almost forget the write, that I could boot with iMacPro1,1 and with iMac15,1, both work with GT710.
The attached config.plist is made for install Big Sur.
