MONGODB-AWS auth method in FIPS-mode

Hello everyone.

I have a question regarding the MONGODB-AWS authentication method in combination with FIPS-mode.
This page lists all safe methods for FIPS-mode However, the above method is not there.
And I am wondering if there is any particular reason why it is not safe to use it in FIPS mode?

Thanks in advance!

To be more precise, my question was about why this method is not listed there?
I do not know if it is safe or not, I wanted to know the reason why it is not there.
Is it because it cannot be used in FIPS mode or did someone just forget to add it there and it can be used?
