LAG on switch SFPs to Router SFPs

I was trying to set up the two switch SFP ports in LAG via the combine port type, to the two SFP ports on the router. The switch is showing it is down due to loop, i could not find a similar port setting in the router. I am thinking this is just by design that the ports dont have this option. Correct me if i am wrong but “any” port on the firewall can be “any” type? will we see this in the future? I dont really have a use case, was just bored and wanted to try it out lol
