Do I need to use a supported SMBIOS to update from Monterey Beta 4 to Beta 5?

My normal SMBIOS is iMac15,1 which is unsupported in Monterey. So I changed it to iMacPro1,1 (which is supported on Monterey) to update from Big Sur to Monterey.

After the update, I changed my SMBIOS back to iMac15,1 (because it's more stable) and disabled compatibility checks. Everything works fine on Monterey (iMessage also works).

My issue is that I'm now on Beta 4 and Beta 5 has already been released. When I go to settings, it says there's no update available. Do I need to use a supported SMBIOS (iMacPro1,1) to update my hack from beta 4 to beta 5?
