Depending on your definition of “using”, you may not actually be able to, at least for now. If CPPReference's table[1] to be believed, there are still important features that are either missing from GCC and Clang or implemented “partially”, which may mean different things for different features and compilers. In my personal opinion, unless you're doing the project just for fun, it seems better to stick to C11/C17, at least for the next few years.
