I knew I couldn't be the only techie who took up button accordions (though diatonics in my case). Luckily my flat is very soundproof, so I can get away with it, however I do know of a guy who is one of the main people restoring the English bagpiping tradition who had a similar problem.
Rather than getting digital pipes, however, he filled his wardrobe with bedding/duvets/pillows and would practice them by sitting there with the pipes stuck into a wardrobe.
Roland do actually make a diatonic model of their accordion, and it's pretty popular, however it doesn't work quite as well as the chromatic models due to the eccentricites of that particular instrument.
Edit: Ah ha, as I thought the FR-18 diatonic was in fact discontinued. It's a shame, as it does actually have quite a few fans, but the market is much smaller than for the chromatic models: https://www.roland.com/us/products/fr-18_diatonic/
