You can disable the Protected View in Office through the Registry. The process is similar for all the Office apps, Word, Excel, PowePoint, etc.
1. Open your profile and go to the “Additional Registry Values.”
2. Add a new entry.
Registry Location: HKEY_CURRENT_USER
Registry Key: SOFTWARE\Microsoft\Office\16.0\Excel
Value Name: DisableInternetFilesInPV
Value Type: REG_DWORD
Value Data: 1
Registry Location: HKEY_CURRENT_USER
Registry Key: SOFTWARE\Microsoft\Office\16.0\Excel

Value Data: 1
Registry Location: HKEY_CURRENT_USER
Registry Key: SOFTWARE\Microsoft\Office\16.0\Excel
Value Name: DisableUnsafeLocationsInPV
