keep on-premise exchange server after hybrid move migration to exchange online

Hello I've inherited a network where they have mailboxes in exchange online (cloud) and also have on-prem exchange 2016 server still running . (no mailboxes left on-prem. )
MX records are Exchange online. I'm not sure why the on-prem server is still running . Is there any best practices I can do in order to determine whether or not it's still actually required for anything? Do i need to analyze the hybrid connector somehow? Should I just power it off? What is the best practice in this scenario.
