Agilex 5 GTS Reference Clock Buffer Protection

While reviewing the Agilex 5 GTS documentation, I found that the Input Reference Clock Buffer Protection mechanism automatically disables the reference clock buffer when the input clock is not toggling, and that the documented recovery methods are either reconfiguration or a buffer turn-on request.

For an Agilex 5 design, I would like to clarify:

1. Is there any supported method to keep the GTS reference clock buffer permanently enabled?
2. Can the Input Reference Clock Buffer Protection mechanism be disabled?
3. Is there any alternative to repeatedly issuing a Buffer Turn-on Request when the reference clock may stop and restart during normal operation?
4. If not supported, is the documented re-enable procedure the only recommended approach?
