At least if you are willing to build your own Qt, these should do the trick:

configure … -no-securetransport -openssl-runtime


configure … -no-securetransport -openssl-linked

You’ll probably have to bundle OpenSSL to be sure to have it available, in the right version, on all macOS versions you need to support, so -openssl-linked might be the way to go.
