Yes, once you have installed Catalina and modified the EFI, you can install the combo update like a normal update.yeah I got it, it's a pain in the ass! Tried already your suggestions, no go!
Anyway I found a Catalina 10.15.0 from October 12, 2019, seems ok.
Doing the process right now, will report results.
Anyway, the combo can be installed after I have done the Catalina installation and modify the EFI?
Like a normal update?
