If this feature is not going to be used, I would try running this command: Dell(conf)# eula-consent support-assist reject Let us know if this helps. 
Everytime I log in to my MXL stack I see this:  The SupportAssist EULA acceptance option has not been selected. SupportAssist can be enabled once the SupportAssist EULA has been accepted. Use the: 'support-assist activate' command to accept EULA and enable SupportAssist. How can I disable this?
