@Yahya Shareef Unfortunately you cannot use the HEAD method as it is not supported with the HTTP trigger. Currently only supported methods are GET, PUT, POST, PATCH or DELETE as mentioned in this document. Feel free to raise the feature request here for supporting the HEAD method in HTTP trigger.
The workaround would be calling any service in between (such as APIM or function) which can call your HTTP service with the HEAD method or if feasible you can change the backend calling service method apart from HEAD.
