can't you just start it away from the house?
There used to be a device called a dB Snorkel that acted as a secondary muffler. I also vaguely recall someone using an ATV muffler or something like that after the stock muffler. Definitely would be cool to have one if it doesn't kill the power output, or if you could put it on and take it off without jetting changes.

I have an across the street neighbor who has a Harley, it is not the loudest bike nor the quietest, he starts it and leaves for work at 6am, when the weather will be nice. He sometimes does the bar run with his buds, and comes back way after dark. It's life.
I haven't had a complaint about my bike yet, and probably never will, because we all understand someone can't throw the first "stone". If someone complains, it's game over and everyone is guilty in some way of "transgressing" against their neighbors. Dogs barking for hours outside, kids running into the street without checking, gas powered trimmers (the worst), one guy working on his house until midnight two weeks straight, power tools , table saw and all. Jeez.
The TW is a very quiet bike. Just ride.

Anyone use the DG quiet inserts?....rejet in order if installed?
The comments about use of higher gears is informative but the Original Poster TeeDoubleUTwoHundred's question was about limiting the noise emissions during warming up, likely in neutral.
Certainly a copper 3/4" elbow helped my exhaust note. I tried a 1" elbow for awhile but thought it actually made things a bit louder so removed it. My other TW features a secondary muffler welded behind the OEM silencer, it marginally helps reduce sound at idle but I feel it is not worth the effort.
Certainly things like the db Snorkel can help but they are pricey and a quasi-permanent installation.db download.jpeg
However for just a few dollars one can get 5 to 10 feet or more of some very thin wall tubing to slip over end of OEM exhuast just for the warm up period. Discharge end can go outside directed away fro household. It really works as each exhaust pulse flutters down the tubing dissipating in intensity. Get the thinist wall possible like the drain lines for swimming pools. Warm up is usually not needed for me O.P's warm up is likely short enough that there is no damaging heat build up to the tubing.

What about having a length of tube/pipe and attach that to a small inlet car muffler? I was thinking any cheap 4 cylinder car muffler should do the trick, or would something from the 6/8 cylinder world be better at suppressing the sound?

A half foot piece of tube (or a can with a hole punched in the bottom) loosely packed with furnace insulation works really well when just slipped on during warm up.
I had a DG pipe on mine and after the neighbors started complaining I made one to use while warming up.
