Using er patcher with other launch properties

[Larlenn]

I really want to use er-patcher with another launch properties and mods for Steam Deck
Currently using:
echo "%command%" | sed 's/start_protected_game/eldenring/' | WINEDLLOVERRIDES="dinput8.dll=n,b" sh

How would I combine it with er patcher ultrawide only? Tried after | but did not work

Thanks

this sed 's/start_protected_game/eldenring/' can be removed since er-patcher already disables EAC
so it should look like this
python er-patcher -u -- env WINEDLLOVERRIDES="dinput8.dll=n,b" %command%
