It seems possible for MacOS indeed. Have a look at this script:

I haven't used it myself. Good luck.

I've already found that script, but will it depends on ReFind ruuning the script manually every time computer boots.

From their GitHub page:

Important Note: Compatibility​

This utility has been successfully in use for several years on an MacBook Pro (Late 2013) running macOS Big Sur. Since uploading this EFI-Utility on Github it seems other people got it working too. For example on Macbook Pro 2019 16'. Please read the other Success-Stories on the Issues-Page or consider writing one yourself (please fill in your System Information) in case you found this Utility helpful. This tool doesn't work on Apple silicon Macs.

Important Note: Other Solutions​

A possibly more user-friendly tool to use to disable RAM-Areas before booting into MacOS would be using the "Open Core Legacy Patcher". You configure your defective RAM-Areas in the config-file of OC and there is no need to use the utility
