U/L 20 Rep Squat Question

Hello i have a question regarding 20 rep squat twice a week.

I run an upper-lower split tipical 2 on 1 off 2 on 2 off.
On lower body days tho after the 20 rep squat i am so out of gas that my deadlift and every other exercise after that suffered a lot and i also get a bit of a lower back pain if i deadlift after the 20 rep squat.

Would it beneficial to skip the conventional deadlift and move it to upper body days, or maybe dont do 20 rep squats twice and have a deadlift oriented lower body day?

Skip deads for 6 weeks and lay it out like this…
