Not an expert, but I have heard that this isn't a big deal for the snake. Scaleless rat snakes (which I believe the picture to be) have been found in the wild doing pretty alright. There is a benefit to be had from scales, but in captivity I imagine it is alright.
Pretty sure I heard it from a video by All Canadian Reptile Girl
In captivity it's fine, however some scaleless morphs are detrimental to survival, there are no safe scaleless ball python morphs for example, this is a rat/corn snake, they have one of the benign ones
