Thanks I found that. The problem is that as a a non-specialist this is rather daunging:
Click Add again. The Add Row OMA-URI Settings opens. In Add Row, do the following:
- In Name, type a name for the rule.
- In Description, type a brief description.
- In OMA-URI, type or paste the specific OMA-URI link for the rule that you are adding.
- In Data type, select String.
- In Value, type or paste the GUID value, the = sign and the State value with no spaces (GUID=StateValue). Where: {0 : Disable (Disable the ASR rule)}, {1 : Block (Enable the ASR rule)}, {2 : Audit (Evaluate how the ASR rule would impact your organization if enabled)}, {6 : Warn (Enable the ASR rule but allow the end-user to bypass the block)}
However I did find this https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/customize-attack-surface-reduction?view=o365-worldwide which could help and also this https://support.microsoft.com/en-us/windows/add-an-exclusion-to-windows-security-811816c0-4dfd-af4a-47e4-c301afe13b26
