cant cancel scheme/protocol redirect when accessing the admin UI

I have solrcloud + zookeeper behind a reverse proxy which is doing https termination.
Problem is when asking for solr's admin UI solr keeps redirecting me to http, I considered changing the urlscheme to https but then internal connections behind the proxy won't work.
Is it possible to cancel the scheme/protocol redirect only? I still want to be redirected from / to /solr/
I'm using solr's official docker images with a helm chart deploying to openshift.
basiclly I want http://my-solr/ to forward to http://my-solr/solr/
and https://my-solr/ to forward to https://my-solr/solr/
