I started hrt because I didn't want to grow facial hair. Why do you want to? Also fwiw basically all changes are reversible and can be hidden for as long as you want (with the help of short hair, hoodies, etc.), so if it doesn't work out, it doesn't work out.

E: also you'll still be depressed unless your depression is just from gender dysphoria. You'll be you and feel like you. Reports of people feeling and acting different isn't because of the drugs themselves, it's their depression and dysphoria being alleviated, allowing them to feel and act and look as they wanted.
