OpenCore 064 cannot boot LG Gram 17

Got a 17 inches from Costco on sale with 10th Gen i7-1065G7, upgrade RAM to 40GB and switched out the old NVMe M.2 with a 2 TB. Windows and Manjaro worked well. When I tried to install Catalina or Big Sur with OpenCore 064 and all latest kexts as well as custom SSDTs, I cannot get pass this screen:

I tried everything listed in https://dortania....#stuck-on-eb-log-exitbs-start

Has anyone experienced similar issues?
