MSI GF63 Thin 9SCXR - Booting BigSur! Couple of problems though?

MSI GF63 Thin 9SCXR

Successfully booting BigSur! However...

Can't boot without USB EFI? --- help wanted please:
MSI won't show the OpenCore SATA HD as a boot option after updating EFI. Checked BIOS settings and updated without success. Full OS install boots fine from USB OC. Hard drive won't show as an option in BIOS? Separate windows NVMe booting and showing fine. (Windows EFI as a OC replacement will show 2nd Harddrive)

Other problems:
- no battery status (read I need batt.aml)
- no on board sound yet
- trackpad not detected, however semi-working but won't left click (read this could be battery AML related) will try sorting USB config.

Working:
- Bluetooth
- WiFi
- Display brightness

This is my second OC build; Catalina AMD desktop first attempt was far easier I have found. Laptops seem slightly more complicated? (integrated battery/keyboard/mouse)
