I was able to get past the "BIErrorDomain error 3" issue in Parallels as follows:
On a real, supported Mac, run this command in Terminal:
ioreg -l | grep board-id
2. Make a note of the board ID (mine is Mac-551B86E5744E2388, for example)
3. Run this command in Terminal:
sysctl hw.model
4. Make a note of the hardware model (mine is MacBookPro14,3)
5. In the VM configuration, under Hardware -> Boot Order -> Advanced Settings -> Boot flags, enter the following (inserting the information noted above where shown):
devices.mac_hw_model="<model>"
devices.smbios.board_id="<board ID>"
That should be enough to allow the installer to proceed.

I've found that installing Parallels Tools results in the Big Sur VM hanging at boot, so you might want to avoid doing that (or at least create a snapshot before trying it).
