If you do not compete, every lift is optional. You can do just fine without doing any deadlifts. I generally prefer my own programs to prefabs. But I am a big fan of the “push-pull-legs” splits.
You could try something like this, switching out RDLs for hack squats or lunges or cardio or whatever.
Some more ideas here, subbing for DLs. Rowing and pull-ups have some of the benefits if you can do those.
