That's a lot of volume, It kinda works since its once a week but you might make better progress if you cutback. Also rotate rep/sets/%. An easy example would be one week 5 x 5 the next week 3 x 3. Repeat ad infinium.
Instead of just doing more of the same Deadlifts, if you want to do more add a variable to make your lift better in some quantifiable fashion. Such as a pause mid lift, or no grip compensation (if you use something like chalk, straps, or mixed grip). Doing these things allow you develop other qualities of the lift and limit the weight you can use while still increasing frequency to drive your efficiency at the lift from practicing more often, without burning out. I am doing this soon with both Deadlifts and Squats. Adding Pause Deadlifts after my Squats, and Tempo Squats after my Deadlifts.
You should keep some of the cardio ab work but cut back. Maybe 1 day a week of cardio+abs for maintenance. Pick your favorites and stick to those or rotate the work based on what you want to do on that day as long you get work done.
Something I would recommend, especially if you cut back on the cardio+abs days is lifting 4 times a week instead of 3. The 2nd lift of your Push day is getting stunted by the work done before it. If you don't want to do that then every 4 weeks or so you can rotate which one goes first. This changes it from a PPL routine and makes it closer to an upper/lower but oh well
