dequeue custom stylesheet

I noticed that wp-members loads your child stylesheet again if you declare it as a custom stylesheet in the options.

I get the whole option of having a separate custom file, but I really just want it to use my default styles, and I don’t want it loaded twice. Is there a way to opt not to load any stylesheet for the login/registration form?
