I have a Dell Latitude 7390 at work. According to this compatibility list, the device should be supported, but checking the manufacturer's site it seems to be an option.
Checking the USB-C port, it only has the DisplayPort logo (I thought initially it was some Dell smaller logo). No Thunderbolt arrow.
Can I call it as not having Thunderbolt 3 support? Is there some way of testing if it has or not support?

If you can access notebook’s BIOS, have a look at this:
Systems that have optional Thunderbolt 3 capability will have a USB/Thunderbolt configuration option listed in the BIOS regardless of having a Thunderbolt 3 option installed.
If the system DOES NOT have Thunderbolt 3 capability, the thunderbolt options will be grayed out and cannot be selected in the BIOS.
(From Some Systems with USB Type-C Port Lack a Thunderbolt 3 Controller.)
