I've just started dual-booting Kubuntu alongside Windows 11, but I'm having a tough time with GRUB as it often breaks and gets annoying. I'm considering if I can uninstall GRUB and just rely on my BIOS menu to choose which OS to boot into. My plan is to set Kubuntu as the default since I use it daily. If I decide to use Windows, can I just change the BIOS settings temporarily to boot into it?

I'd like to know what issues you're facing with GRUB, since it's pretty reliable with Ubuntu. Some folks do prefer rEFInd for its features, but for many, GRUB works seamlessly.
You actually can't totally uninstall GRUB, but you can use your BIOS to select the OS at boot. Something I've done is unplug each drive while installing the other OS. Once both systems are installed, plug everything back in and use the BIOS to pick which one to boot. This method keeps GRUB for Linux and uses Windows' bootloader for Windows, and it should still work fine today!
Windows updates, especially with Windows 11, can really mess up bootloaders like GRUB. I've heard that if you boot into Windows and use *msconfig*, you can add your Linux boot option to its menu and set defaults and timeouts there. Just keep in mind that you'll probably have to reinstall GRUB if you ever stop using Windows.
Unfortunately, Ubuntu requires an intermediate bootloader to start, so you'll need GRUB or a similar option. The entry you see for Ubuntu in UEFI settings leads to GRUB. You might want to look into getting rEFInd, which can be another boot manager that might suit your needs better than GRUB. But remember, removing the GRUB package won't wipe GRUB off your EFI partition.
