Change Sharepoint site of Learning Content Repository

How do you change the Sharepoint site where the Learning Content Repository list is located?

When accessing Viva Learning -> Admin -> Manage providers -> SharePoint -> Edit, there is a field to "Enter the URL of the SharePoint site for your organisation's learning content catalogue" which is prefilled with the address of the Learning Content Repository list's current site. However, this field is greyed out and below it is the message "This is a non-editable field." So where/how can this URL be changed in order to re-locate the Learning Content Repository?
