I personally solved it via some Loctite like was mentioned. Apply a little to the OD of the bearing and press it in.

Example, my BB86 in my foil, cranks slipped/bearing came loose. I had put the wavy on the ND side, like my BB30 setup. Well, that is wrong for my S975 Quarq, the wavy goes drive side, no spacers on the left, torque to spec, no problems.
The cranks and torque of the bolt hold the bearings pressed into the frame. At most, they would only creak if they can wiggle slightly while standing on it with some power.
They should never slip/move around the bearing left/right in the frame or cups when spaced, torqued and installed correctly, whatever the instructions say for your cranks/bearing setup. If it does, and everything is correct and it creaks, then loctite 609 will solve that.
But if the bearing diameter is off .1-2 mm, that could cause creaking also, but it wont move side to side still. That is a spacer, torque wavy issue IMHO.
Verify proper install and torque. Then I would take it to the Trek dealer or call them and find out what the deal is.
You never said what cranks you have.

If installed correctly, then get in touch with the Trek dealer and ask about the v2 bearings people have mentioned.
Even .1-.2mm can make a big difference in how snug/tight the fit is. You still might need loctite 609 to get it real tight/secure.

Do you want to heat your carbon frame up to that temp? I wouldn't on mine. Many manufacturers tell you not leave your frame in a closed car on a hot day! Just like your dog, it may die.
I was skeptical when Trek brought out the all carbon BB and am even more so now that I see they have special oversize bearings and shims for out of tolerance bottom bracket moulding.
The TDS also says that Loctite 609/641 is not recommended on thermoplastics. The fact that it may be recommended by various manufacturers leads me to assume that these designs are having service issues. I work in the automotive industry and most of the gap filling/sleeve retaining Loctite type products require heat and or quite a bit of force to take them apart. Pounding or rigging up an elaborate puller on a lightweight bottom bracket with little material to begin with seems like asking for trouble.
However, you may be left with little choice but to use these products so you have a useable crank/bearing assembly. But it may make for a trashed frame when it comes time to replace the bearings.
