FreeRadius dynamic DB secret with vault

Hi All, I am using FreeRADIUS 3.2.6 and want to do the dynamic DB secret with Vault. I failed to use the console socket to send a SIGHUP signal to reload the SQL module when the DB secret changes. It seems that not all of the modules support reloading. So, I wonder if there are any ways to reload the SQL module or support the dynamic Vault secret. Thanks.
