Have you looked into third party apps? I’m very personally used the app diabox (on android), I’ve heard suggah (if I spelt it correct) also supports a nightscout link like diabox. However I’m not sure how these work with dexcoms.

You probably know all this as well, but for future googlers:

I used to use Libre + MiaoMiao + Nightscout, but these days I much prefer Dexcom G6 + xDrip + Nightscout.

Pros for the G6:

- No 3rd party transmitter (e.g. the MiaoMiao)

- It's smaller and can go on the stomach so it's less likely to get ripped off

- 1 less app involved -- xDrip integrates directly to Nightscout and there is no need for the Dexcom app

- Supposedly the glucose readings are a bit more accurate than the Libre

Cons:

- Sensors are more expensive than the Libre

- The transmitter is not rechargeable so you need to keep buying them every 90 days
