networking rhel drivers network-interface

I have a Dell PowerEdge R740 server with an Intel Corporation Ethernet Controller x710 for 10GbE SFP+ network interface. I have installed RHEL 8 on it. I am trying to enable UDP Fragmentation Offload (UFO): $ sudo ethtool --offload eno1 ufo on I get this message:

Cannot change UDP fragmentation offload  
Cannot change any device features.

eno1 has SFP+ DAC cable. Is the issue because of SFP+ cable? or any driver that I might be missing?
