Highly likely your UX390UA is CFG-LOCKed so you have to unlock. Here is how to unlock.

Donwload modified grub.efi from following page.
https://github.com/datasone/grub-mod-setup_var/releases
Put the "modGRUBShell.efi" to EFI/OC/Tools folder(You have to update your config.plist accordingly).
launch modGRUBShell.efi from OpenCore boot screen.
Execute "setup_var_3 0x4E4 0x00"
That's it! Now you have CFG-unLOCKed UX390UA ready to install macOS.

In case of want to details here is deeper info about "CFG-LOCK".
