SAT Writing Section for Schools that do not consider it

I am currently a high school senior who has already committed to a university. I can receive a better scholarship if I improve my SAT score, which is currently
CR: 620
M: 700
WR: 750

The university super scores and only looks at the Combined CR+M. So, would it matter if I were to say bomb the writing section (as in just bs the essay and not think hard on the MC to avoid stressing myself out for the CR and Math sections that matter)?

Thanks in advance for the help

You can do SAT without the essay portion for your scholarship, yes? Never intentionally bomb anything.
