How to connect to a remote Maven Repo with TLSv1 only on Nexus 3?

we are trying to connect a Maven Proxy repository to a remote repo which unfortunately supports only TLSv1.
When Nexus 3 is trying to connect we get the error message “Server chose TLSv1, but that protocol version is not enabled or not supported by the client.”
I’ve already tried to enable TLSv1 support by setting “-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2” or “-Djdk.tls.client.protocols=TLSv1,TLSv1.1,TLSv1.2” in the java options, but those didn’t work.
Does someone have an idea on how to enable TLSv1 in Nexus 3 for client connections?
We are using Nexus Version 3.20.1
