Need to understand deployment and set up of openshift 4.3 on vmware vsphere

Hello Team

I am looking out to set up openshift 4.3 on vmware vSphere environment where i have no vSphere admin credentials..

Could you advise the best possible way to set up in disconnected mode where sysadmin can provide VMs so that end non admin user can set up openshift 4.3.

Please advise.. they were blockers to me
