How to removed CMDB Workspace option from banner?

[JordanDR]

Is there a way to remove the option for "CMDB Workspace" in the banner? Currently testing the new San Diego release in sub-prod instances and was wondering if there was a way to remove this.

This was indeed the way I was able to remove it.

Many thanks!!

Thanks so much, It helped me.

I was able to deactivate it in the UX Page Registry.

Thanks for the URL. 
I now am able to remove workspaces from the top menu item.
However I would like to remove the complete "Workspace" menu from the top as we are not using workspaces at this moment but would like to use the Polaris ui.
Is it possible to remove the complete menu from the top?

I was able to do this, by disabling the OOB Business Rule: "Avoid duplicate menu configuration"
Then i opened a background script and ran it:

var gr = new GlideRecord('sys_polaris_menu_config');

gr.get('<<Insert Sys Id for the menu you want to disable>>');
gr.active = false;
gr.update();

Then i re-enabled the business rule.

This made my menu go away, and i can easily bring it back by reversing the steps above.
