Thank you so much for this. I wish it wasn’t a crude way, but it works.
To those curious and a pixel artist like me,
Right click the Vector text you want to “disable the anti-aliasing” of.
Add → Filter Mask
Adjust → Color Adjustment → Channel: Alpha
Then put Input to 0 and Output to 255. Here’s a picture for those who wants to save it.
