I haven’t seen a DIY.  I replaced mine chasing down the infamous Boxster howl.  It’s not hard as the canister is easily accessible from the front passenger wheel well. The real problem is that there a few variants in evap canister over the years so you need to know which part that you need.  This can be decoded from your VIN.  When I replaced mine it was an hour tops with most of the time spent disassembling and reassembling.  I did weigh my old and new canister.  The old canister weighed a whole pound more than the new canister.
