I am a bit lazy and trying to manually recreate a cluster I have in one workspace into another one.

The cluster was created some time ago. Looking at the configuration, the access mode field is "custom": 

When trying to create a new cluster, I do not have this option. I have 3 others but not custom.

Is this a new option added recently or I did something wrong in a configuration?

Ideally, I want to have this option configured the same way as in my existing cluster

TIA
