If I purchased a Mac book pro could I use high Sierra for the operating system
Can I use high Sierra on the new Mac book pro 2020 instead oh Big Sur

Sorry, no. That won’t be possible. No Mac can run a macOS version that predates the one that was installed when it shipped.
That’s is to say if a Mac shipped with Big Sur installed, then it will be incapable of running any earlier version of macOS.
