How to dual boot ubuntu and mac os without refind?

[lzy917]

I'm trying to install ubuntu on my MacBook air 2019 with Catalina 10.15.6. But my MacBook has the secure boot feature which doesn't allow refind to work at all and I'm not feeling comfortable to disable secure boot, so is there any way to dual boot without refind?

I don't have Catalina installed, but I see this addressed here:

Disable Secure Boot prior to installation, through Recovery Mode > Terminal "csrutil disable"
After refind is installed, reverse the operation > Terminal "csrutil enable"
