[MCU] How do the TVA approach the situation when they have to arrest a Variant who has Infinity Stones?

Once they bring the variant over to the TVA headquarters, the Infinity Stones don't work. 

But the TVA need to initially arrest and transport the Variant there to begin with. So what is the game plan when a team of TVA agents need to enter a universe and stop an Infinity Gauntlet-powered Thanos Variant?

The single most overwhelming force multiplier is speed.  Very few techniques or defenses are truly instantaneous, and even those require that the threat be detected.  Someone who moves fast enough can disarm and incapacitate an enemy before they even realize they are in a fight.

The TVA's time compression technology lets them freeze a target in place, preventing them from taking any action.  From there, they can simply portal the target into a secure location and disarm them.  We know implicitly from the success of the TVA that no alien or superhuman is beyond their power.

(At least, until we get Squirrel Girl in the MCU.)
