Can I run PEX through these ceiling joists?

I am a first time homebuyer and was just informed by the inspector that the slab foundation house still has Polybutylene pipes w/ copper fittings that run through the slab. I was hoping to be able to replumb the house with PEX through the attic but I wasn't sure if I would be able to run it through the joist or if I needde to lay it on top. I know you shouldn't drill through trusses but I am still unsure from the layout of the attic. Can I drill through these ceiling joists to run PEX through? https://preview.redd.it/fri6ln0n78re1.png?width=1078&format=png&auto=webp&s=675e264ee2ea6e6e3dda89f09130acb8f255ddd0 submitted by /u/geeshmee [link] [comments]
