Does my Mac support 'DisplayPort Alternate Mode' so I can use a KVM?

I'd like to buy a new monitor and have been looking at models that have an in-built **KVM** switch functionality as this would both reduce cabling/connections and enable me to use the monitor for home and Work-From-Home easily. I'm aware I could get a separate KVM , but one that's already in the monitor seems ideal. I have a home MacMini (2020, M1) and a work MacBook Pro (16" late 2019, Intel) . Both have USB-C connectors with Thunderbolt 3 which both state: > Native DisplayPort output over USB‑C in the technical specs (linked above). I'm aware that I may need specific cables such as Apple Thunderbolt 3 (USB-C) Cable _Before buying the monitor_, is there any way to verify that at least one of the Macs has the required feature/signalling to communicate to the monitor so that it can use the KVM feature? This whole question was brought up by a review of the monitor which mentioned the DisplayPort Alt Mode issue.
