Alternatives to flip turns for freestyle

I am pretty new to competitive swimming and have been doing quite well in every aspect besides my flip turns whilst doing free style. I was wondering if I were to use some other kind of turn while doing free style (still touching with two feet) would that that be legal or could I potentially get disqualified? I understand the importance of flip turns I just feel like mine aren’t very good at this point and using different methods of turning is much more effective.
