i'd stay away from arm isolation workouts if i were you. use the time to do more compounds instead

Not really. If you're trying to lose the fat, doing more compounds will help by

1) building/work on more muscles which translates to you burning more calories, during and post workout. Your chest, back, legs are big muscle groups (bigger than arms at least), which if you focus on building them/getting stronger, will reward you with higher metabolism = higher bmr/tdee.

2) you'll work your arms alongside anyway. So it's killing 2 birds with one stone.

It's just a suggestion though.
