I think there are some additional changes that can be applied and tested:

• .evergreen/config/functions.yml refers to the local x509gen directory several times. Those references can be changed to tests/drivers-evergreen-tools/.evergreen/x509gen.
• .evergreen/orchestration only contains a single basic.json file for a sharded cluster, and that doesn't appear to be referenced anywhere.
• .evergreen/auth_aws doesn't appear to be referenced.

@jmikola What I don't understand re: the x509gen references is that they're from the same exact commit as references to x509gen in the submodule a few lines later. That makes me feel like maybe there's a reason that points to the local ones

[paulinevos]

@jmikola Oh actually, they aren't references to the local one at all:

cd ${DRIVERS_TOOLS}/.evergreen/csfle

I'll see if they're referenced anywhere else and otherwise remove

[jmikola]

Thanks, I missed the cd command in functions.yml.

Changes LGTM. I'll defer to you on the tests.yml change.

And please revise the PR title before squash-merging, since the PR addresses more than just OCSP.
