nonee I think disabling wurst from Statistic Screen removes it from everywhere making Wurst completely an unusable Ghost mod until you reenable it.
There is always a way to completely disable it from statistics screen but if you want to use Wurst while also hiding it, you need to follow these stuff written below,
1. Disable all ESPs.
2. "Shift" to go to wurst menu, then search "WurstLogo", click it and select "Only show when Outdated"
3. Same way, Search "Hacklist" and then select "Disable"/"Hide"
This should do the work. But remember that it's not completely ghost.
There will be "Wurst Options" on Title Screen & 'Esc' screen.
So if you mistakenly show that up, you're doomed.
If you don't want to take any risk, the only option is to Disable it form the Statistics screen.
