After the fact, if large loans are an issue, Teach for America could address that:

But one must be committed to such a post-grad program that would allow forbearance or deferment:

The TFA website is also clear that monies available are not secure at this time. And they might need to prioritize those receiving any grant benefit.
What you want is loan forgiveness or partial cancellation. Forbearance and deferment do neither.
If you need loans, another option that you have is an educational line of credit. When you’re approved for the first time you are approved for a large sum all at once. Then each year during particular periods I know ones in the summer, you go to the providers website and request to draw the amount you need from the available balance. So you know your approved for the money, your just waiting until you need it to take it out.
I know my credit union offers this. They do it in partnership with student choice. From student choice website you can look to see what banks/credit unions near you that you can use to apply.
