Dual-Booting Ubuntu and Catalina

Hello everyone. I have compiled my EFI folder to have all the kexts and everything I need, and I'm ready to start installation. I have partitioned me 1TB drive into a 400GB partition for Ubuntu (already installed) and 600GB for Catalina. My question is what do I need to do to the EFI partition that is already on my drive? I also have Grub bootloader installed, if that changes anything. I'd like to get grub removed to only have MacOS boot, and the option to boot ubuntu in the BIOS. Thanks in advance.
