Here are some steps that may help.

Erase your Mac.
- If you would like to keep the data, add an APFS volume. You cannot install macOS High Sierra on the same volume as macOS Big Sur; downgrading is not supported in that way.
Reinstall macOS from macOS Recovery.
- There are different Mac startup key combinations depending on which version of macOS you would like to install.

If you choose the option for multiple volumes, you can switch between macOS High Sierra and macOS Big Sur with Startup Manager.

When using internet recovery the newest macos will be downloaded.

Try SHIFT OPTION CMD R, for the original macos that came with your Mac (or closest still available)
