How to downgrade OpenSSL in buster image Airflow 2.0

Hello dear Astronomer Team,

We are using following Docker image of Astronomer 2.0 build

This Debian 10 buster version contains openssl 1.1.1d, whilst it is critical for us to have version 1.0.2k-fips installed, because our email server has such openssl version and we can’t send an email. I.e. smtplib.starttls() command in python3.7 throws an error.

How can we downgrade openssl from 1.1.1.d to 1.0.2k-fips. I tried many things, no success.

Thanks beforehand!
