I have the same problem but on a ASRock NUC 1165G7. The same install USB flash will boot on a 10 gen Core i7 Dell notebook. What I did was install 20.04.1 Ubuntu on the NUC 1165G7 and then install the OEM kernel or HWE kernel. It runs then, but there are some GFX issues. The Linux support for the 1165G7 is not completely baked yet, IMHO
