Does "Full-Sector DFS" automatically work if the EAP245s are only hardwired? In this scenario the DSF selection box is not available. 

No, it only works for EAPs in the mesh network.

Here is the explanation to "Full-Sector DFS" in the UG of Omada Controller v4.2 for your reference:

Will DSF work if the EAPs are hardwired and the Mesh and DSF boxes are selected and does the EAPs radio channel selection need to be on Auto for DFS to work? 

At present, EAP245 with US/CA version doesn't support DFS channels. If your EAP245 is EU version, you could leave the channel as Auto(the device will detect and select a clean channel when it's rebooted), or select a DFS channel manually.
