Access Nexus Repository from Jenkins bypassing SSO

We are using Nexus Repository Manager OSS 3.251-01
For authentication, we are using Shibboleth. We are covering the whole application by SSO. We are authenticated by header. I want to find a solution to be able to pass SSO and access Nexus from Jenkins to upload artifacts.
I am interested maybe there is some plugin or other solution to make an SSO bypass connection.
