I'm currently dual booting Mint and Cachyos on my computer. Right now, every time I start up, it automatically loads Mint, but I'd prefer it to boot into Cachyos by default. Additionally, I want to completely get rid of Mint from my system. Can someone guide me on how to do this safely without causing any issues?

You can change the bootloader settings to set the OS you want as the default. After that, consider deleting the partition where Mint is installed and repurposing that space for Cachyos. Just remember to mount the new partition afterward!
Each Linux installation usually adds its own grub or boot loader files to the EFI partition. You'll want to set the default GRUB to the one from Cachyos. It could also be helpful to install `rEFInd` as an alternative boot loader. First, check what’s on your EFI partition since you may have multiple entries. Once you choose Cachyos as the default, you can safely remove the Mint partitions and its GRUB files from the EFI.
You can locate the grub.conf file to make the necessary changes, though I can't remember the exact path off the top of my head. A quick search should help you find it. Also, using a tool like grub customizer can make it simpler to change the default and remove entries you don’t need. Just keep in mind that there might be multiple grub.conf files.

Actually, it might be easier if you delete the Mint partition entirely and merge the space with Cachy’s root partition.
