Did you try the ones from DJI downloads (in the > Software > Transcoders section)? There is a D-Log to Rec.709 for every device that supports D-Log; good place to start, then modify to your tastes.
I have been looking at The Film Poets(Store - Film Poets) LUTS as a recommendation from a friend in the UK. I the DJI LUTS for the Mavic 3 Pro are okay, but don't meet my needs.
Also looking at the NEAT noise reduction.
