The only way I can think of is to tell the Kernel 25% of the memory is bad and not to use it.

This Unix & Linux Q&A has excellent instructions. Here is a snippet:

If there’s bad RAM at 802M and 807M, you can disable a 10M section of RAM starting at 800M like this:

memmap=10M$800M
⇧ GNOME in Ubuntu 18.04 and multi monitor setup `root` owns some files in `/home/user` should I be concerned?  β‡©
