Looks like you have users added via the system group 'account users' to the workspace. This is a system group and cannot be edited. You may make the user inactive at the workspace level using `Users` Patch API as shown below. You may get the userId from the user details page URL  (for eg : 123 being the user Id from user details page :  https://abc.cloud.databricks.com/settings/workspace/identity-and-access/users/123?o=456)
```

curl  --request PATCH '{{workspaceUrl}}/api/2.0/preview/scim/v2/Users/<UserId>' \
--header 'Accept: application/scim+json' \
--header 'Content-Type: application/json' \
--header 'Authorization: <Token>' \
--data '{
  "schemas": [ "urn:ietf:params:scim:api:messages:2.0:PatchOp" ], 
  "Operations": [ { 
    "op": "replace", 
    "path": "active", 
    "value": [ { "value": "false" } ] 
  } ] 
}'
