Hi 114781753852, not sure if you found a good workflow here but wanted to jump in here with a suggestions.
I’ve been using DxO Photolab for the last few years and just recently wanted to test and see if LR Classic might be better at doing large scale raw processing for photogrammetry where I quickly noticed the issue that you noted in this thread.
I’d highly recommend using DxO Photolab for Mavic 2 Pro datasets. The software detects the body/lens of the camera and downloads a camera profile from their database but you have full manual control over whether you wanna enable the corrections. So it’s easy to disable any distortion correction but enable vignette correction, chrom. aberration, etc.
I also found that somehow the exposures in LR Classic for Mavic 2 Pro photos look a stop or two higher than in DxO and have less room to adjust… DxO is the way to go here.
Anyway, seems like after 2 years, there’s no good way to turn off these lens profile corrections in LR without stripping the exif info as you had suggested… Shame!
