Multiboot into different macOSes, hiding unused partitions?

Previously, I’ve installed different versions of macOS on Apple hardware. Works fine, however since all partitions are always visible Spotlight scans all of them. So, you end up with multiple options when you search for a file with Spotlight.

For Linux I know that you can change the partition type of the bootdisk you don’t use, so it’s unrecognized and doesnt show up.

With a Hackintosh build, are there solutions for this problem? I want to hide bootable disks for the OS when they are not used. I also dont want macOS to ask me if I want to format the disk because it’s unrecognized :-)
