Freeing up space on Athom Plug V3

I bought 8 pcs of the ESP32-C3 plugs. I need to enable MQTT in order to control these directly from Octoprint (to turn on/off 3D printers on demand). This worked successfully in ESPHome 2024.09 (although the storage use was high). With 2024.10 it seems the image has increased in size, so this is no longer possible:

So now I need to slim it down a bit. I'm thinking Improv is pulling in the entire BLE stack and could be omitted, but I can't see how to do it without disregarding the entire default configuration file. Are there any other options than doing that? Other suggestions on how to reduce the image size?
