I installed rEFInd bootloader from Sourceforge, and run the install script. Everything seems to be successful. The install output is
ShimSource is none Installing rEFInd on macOS.... Executing: /usr/bin/kmutil load -p /System/Library/Extensions/msdosfs.kext Installing rEFInd to the partition mounted at /Volumes/ESP Found rEFInd installation in /Volumes/ESP/EFI/refind; upgrading it. Found suspected Linux partition(s); installing ext4fs driver. Installing driver for ext4 (ext4_x64.efi) Copied rEFInd binary files Notice: Backed up existing icons directory as icons-backup. Existing refind.conf file found; copying sample file as refind.conf-sample to avoid overwriting your customizations. Installation has completed successfully.

However, when I hold option key while starting my mac, I am still getting the default apple bootloader. My SIP is disabled
"System Integrity Protection status: disabled." and my T2 protection is also turned off. How would I be able to fix this problem?
Note: I am using 16 inch 2019 Macbook Pro and running MacOs Monterey 12.4. My final goal is to dual-boot Linux
