question for the masc afab ppl

so im currently fem have a bigger chest and i wanted to experiment with being more masculine, is there any way i can flatten my chest without binding ? i want to be more active and ive heard its dangerous to bind for extended periods of time i just want a flat(ter) illusion without having to resort to something as extreme as binding. is there like any bra that i can wear that does the same thing ?

thanks in advance !
