Put a farm tag on it if you don't plan to use it commercially. You just have to sign a form stating you are using it for farming and have 10+ acres. You don't have to physically OWN 10+ acres FYI.
If you plan to drive it often (or over 100 miles from home) I might wouldn't suggest that.
I guess I have never tagged anything over 26k that wasn't a farm tag, so I don't know, but I can't imagine what business it is of the tag office if you have a CDL or not. You could be tagging it for your CDL licensed employee, cousin, or baby mama to drive.
ALSO, the limit for form 2290 is 55k lbs, so keep it tagged for 54k or less and you don't have to fool with filing it. Also, a farm tag is 1/2 the price of a regular tag, and no CDL requirement.
