Refind disappears after OCLP Somona boot

Hello, I've got Somona working with OCLP on a 13.1 iMac. I've also got Linux Mint installed on a different partition.

However, I'm unable to access Refind at startup after booting Sonoma. All I can access is the Sonoma partition.

I think Somona might be messing with the SIP but I've got no idea really.

Please help!
