Actually, as Pope Francis reaffirmed and signed off on - 
Those who "experienced a “transitory” attraction to other men could be admitted to seminaries, it says, again repeating the 2005 document, though “such tendencies must be clearly overcome at least three years before ordination to the diaconate.”  https://www.americamagazine.org/faith/2016/12/07/vatican-reaffirms-ban-gay-priests

I'm guessing close proximity to similarly attracted young men is considered too challenging...therefore - no.
