Infragluteal fold augmentation (Photos)

I have always hated the shape of my glutes. As you can see, the infragluteal folds appear to form 2 right angles rather than a nice, curved shape. I’ve attached reference photos of my glutes vs the ideal infragluteal fold id like to have. I lift heavy weights, eat well, and am generally happy about the overall appearance of my body. I don’t even necessarily want larger glutes, I just want longer, rounder folds. What can be done for this? I don’t necessarily want a BBL/larger glutes
