I do the simple way.
I buy women's panties many sizes too small for me, I should be a L/XL, but I use Small. Wear backwards and pull up tight to partially hold the tuck in. The butt part of the panty holds tuck partially, while the crotch part of the panty goes up a bit into the butt crack....
This is good enough just for wearing jeggings/leggings, eliminates the majority of the bulging for me.
