Yes you can, it's under Graphics, I think.
It's a drop down box that lists what the engine will render while you're in first person: player model (see your feets) and weapons, player model only, weapons only, or none of the above.
There are also scripts out there that will selectively disable the sniper rifle and missile launcher models when you switch to them.
If you just want it per weapon you'll need a script for it. DEbig3 aka Adept wrote one called HideWeapon.
Extract HideWeapon.zip to Tribes2\GameData\base\scripts\autoexec. The script requires support.vl2 to configure via the SCRIPTS option. Place support.vl2 in Tribes2\GameData\base.
