My understanding was that the R750 had integrated Zwave radios, per the product sheet.
The R750 has built-in IoT radios with onboard BLE and Zigbee capabilities. In addition, the R750 is a converged access point that allows customers to seamlessly integrate any new wireless technologies with our USB port.
but if they do not, then I can get the Smart Hub Dongle without too much issue.
Do the features you mentioned need a license?

My use case is setting up home assistant, which is a home automation platform that's locally hosted. I want to be able to manage the Zwave devices that I have here. (Which include things like light switches and outlets.)
