If there would be such option in setting to never see local deployment games, I would use it once and forever, cause I dislike such games so so so so so so much.

Would it be possible to add it? <3 :)

Go here

https://www.warzone.com/SettingsHighlight

check "Highlight if local deployments are enabled"

now when you join a game those settings will highlighted

If you see this icon then it's LD fyi.

Assuming you hate them due to accidental join that is ;)
