On my AMD B550 Vision D the System Product Name is iMacPro1,1 and SBM is also set to “Default”. It is also running Monterey Public Beta 10, and boots up properly every time…I also don't have this problem all the time but if I select Opencore (or Clover 5141) as the boot partition in the Bios, then I get the said message. And even after an NVRAM reset, I must then select OC 0.7.3 on a key to be able to reboot and then go back to 0.7.4 ...
My SystemProductName is iMacPro1,1 (DRM...) (Apple T2 Security), I know I know that with non T2 there is no such problem...
Rather than default maybe I should try with j137, right?
However, it’s okay to try j137.
