This will probably bring down your gpa by 0.01. Based on your comments your gpa is in the high range of 3.75 +, so this should not matter.
From what I have heard before from more experienced ADCOMs any P/F in a science course, they usually equate to a C or worse, unless it is part of the COVID 19 process, where some colleges reverted to P/F for lots of courses. However if the other courses for this semester all have a letter grade, and this has a P/f, then they know it is not covid related change in grading for your college, and they may take this to mean you got a C.
I would keep the A-.
