Can someone please help me make a good split?

So I‘ve had plenty of free time during the summer holidays, but I‘m starting to think about how I could plan my gym routine once school starts. I‘ve been going to the gym for a little over 2 months now and my split consists of just basically upper and lower body. Every time I‘m at the gym it takes me 1,5-2 hours, which might be a little too time consuming once school starts and upcoming exams start to follow. Can someone help me get a better split than just upper and lower body? I plan on going 4 times a week to the gym once school starts:

These are the exercises I currently do:

LOWER BODY

1. Leg press
2. Single-leg leg press
3. Hip thrusts
4. Cable kick backs
5. Romanian deadlifts
6. Hyperextensions
7. Bulgarian Split squats

UPPER BODY

1. Lat pull down
2. Shoulder press
3. Lower back machine
4. Pull ups
5. Biceps curls
6. Triceps bar pushdown
7. Rowing
8. Some specific exercise on the cable machine that my physiotherapist recommended for my scoliosis(idk what the exercise is called)

How can I split this more effectively? I‘m also open to adding or removing exercises to have a better split
