@yallow Consider getting a consult with a Dietitian to help identify any diet or lifestyle factors that may be influencing this but key things to focus on are reducing sodium/salt (recommendation for healthy adults is 2300 mg/day), reducing/limiting alcohol consumption, and reducing /limiting caffeine and other stimulants. A big culprit for the last one is of course pre workouts, you may want to cut those out completely. Cutting out fast food, eating out, and processed food in general will really help with the sodium, some of my clients normally get 4000+ mg/day when they start with me, its pretty alarming...
Also look at how your stress and anxiety levels are and make sure you're getting enough sleep.
During your lifts make sure you are not holding your breath too long as this can increase your BP. Pay attention to any feelings of light headedness or dizziness as these are signs you should take a break and let you BP settle.
In regards to your overall workout routine you can try to alternate upper body and lower body movements to help prevent BP from getting too high.
