Thunderobot 911 Air (Excalibur G770) Advanced settings

hi guys,
I want to access all settings my g770 laptop (Insyde BIOS). Xmp profiles, Overclocking, Power limits etc. normally inaccessible. I want to install a different operating system (linux, macOS Catalina)
I’m wiling to pay to make up for your time
Specifications of my laptop:

24 gb kingston ram
nvidia geforce gtx 1050

Thank You
