If I'm using same disk, yes. Because all the distros will be sharing the same EFI partition. In my case, I only have only 2 distros, old Slackware and new distro, and on separate disk.

I'll test your idea, as soon as I find a spare disk. I just found out CachyOS repository only has 64-bit arm cross compile toolchains. I still have to use Debian VM for 32-bit arm.

More than likely you need to increase UEFI partition on /dev/sda*. Slackware that took my cherries will typically create 100MB (Same as windows) size and that's not enough if you are multi booting or distro hopping and reason is cachyOS + limine (which i use) will copy multiple initramfs and vmlinuz to the UEFI partition to select or revert via multiple kernels with corresponding btrfs snapshots.  Other Linux distro will do roughly the same, except a few like Fedora where it points vmlinuz and initramfs to /boot. This is probably why fedora worked for you.  My UEFI Partition is currently 653MB out of 2GB, where a big portion is only 3 linux kernels + additional files for cachyOS.

What's worse is distro hopping installs will fill your UEFI partition overtime and will not be removed(you have to do it yourself) and therefore, also not go overboard with lots of Linux kernels to install. 

I dual boot cachyOS (/dev/sdc*) and windows 11 (/dev/nvme*). have to manually expand windows UEFI fat32 partition from 100MB to 2GB for multi boot cachyOS or any Linux distro to work.

This issue is not just you... i've encountered this last year too but not well publicized on the internet.
