VY Dra is classified as a suspected variable in VSX. I have some old observations from Zacharov (from 1932) which I could digitize, but I'm not sure if
this is worth the effort.

When I look at the light curve in the LCG, I see a lot of variation. Also SuperWasp gives different magnitudes (

But Hipparchos/Tycho data shows little variation ( I guess this last source is the most reliable one and that VY Dra is a non variable? Are there other methods to confirm this?
