Do you anyone help me by guiding me to some documents as to how you deploy/configure Defender for Office 365 filtering-only scenario for your on-premises Exchange Server?

In MDO delivery will appear as on-premises/external, effectively beyond the reach of Microsoft. So as Don says, no Zero-hour Automated Purge or manual remediations from the security portal. I think those restrictions apply equally to on-premises Exchange and third-party on-premises gear. You definitely want to decide what else will be allowed to talk directly to your on-premises equipment, and whether the on-premises system will be sending directly or back out through MDO. In the latter scenario, I think Exchange Online product limits will apply. However, if you allow on-premises to send directly then you lose the MDO anti-virus tripwire for an internal infection and you lose any outbound compliance / auditing controls you might otherwise gain from the Microsoft cloud.
If you have Outlook clients served by the on-premises system then the Report Message add-in will still work, but that will only help vs later attacks because you have no ZAP.
Hybrid is a fairly big topic and I have probably left a few things out.
