Can I stop my Honor 10 Lite from bleeping when fully charged?

Deathwing

I plug my Honor 10 Lite in to charge while I am asleep but it bleeps when it reaches full charge, which is annoying because it can wake me up. Is there a way to stop it bleeping at full charge? I have tried putting a "Do Not Disturb" on for the night but that does not stop this bleeping.

Many thanks!
