The support for OpenGPG in Thunderbird on RHEL 7 can't be enabled as on RHEL 8 (bug 1886958) or RHEL 9 (bug 2133263) due to older OpenSSL available on RHEL 7 (openssl-1.0.2k is presented and 1.1.1e required).
What customers could use (albeit not supported by Red Hat) is the upstream binary from Mozilla (available through https://www.thunderbird.net/thunderbird/all/). This version uses and bundles different stack that is not available in RHEL 7.
