How to play ghost/dead/muted notes?

I am not sure this belongs in technique. It may belong into Theory. Probably a bit of both because I want to know what technique to use when reading sheet music:

At the beginning there are notes but crossed out and as far as I know you play these while plucking a muted string. Now there’s different ways to mute a string and when someone tells me to play a ghost/dead/muted note I would just mute the string and pluck.
Now I noticed that the X on the sheet music has a pitch and I would assume the correct way to play it is to mute the string but still fret the note so you get the right frequency/pitch but muted.
Now on guitar with strumming I would use palm muting for that. I read in another thread that palm muting for bass exists (why wouldn’t it) but I guess the hand position is different.

What do I do on bass when using the alternate plucking technique with resting thumb?
Is there anything obvious I’m missing?

P.S: This is part of the sheet music the band sent me. There are too many 16th with pauses and switches to 8th overall for my taste at my current skill.
Maybe good to get forced out of the comfort zone though.
