Donor account on 2 profiles
is there a way to apply my donor account to my second minecraft account without using the "alt" feature?
You can transfer the donor status to your other account/alt and remove it from the account you are currently using. (DM @Dyiing for more help and info on that).
Other than that, unless you are buying donor for the other account, you aren't gonna get that to happen unless you use the alt manager to login via your donor account then switch to the alt.
TLDR; You can only have one account with donor status unless you pay for it again and have it applied onto both accounts. OR move your status to a different/new account. (This is my understanding of it)
