Yes you can. No conflict in applying.
I am not sure if this advice is very thoughtful. Yes, nothing prevents you from entering express entry pool and even submit application if you get an ITA.
However, on what basis will you get an ITA is not quite clear to me. You could score high enough in English, education and stuff to meet CRS bar, that I don't know.
But you also need to qualify requirements for one of the 3 mainstream PR programs. FSW, CEC or PNP.
For all major provinces, PNP often asks you to be already here for a while though some provinces allow PNP if you have education from there e.g. Ontario.
For either of CEC or FSW, you need at least one year of experience in your skilled field. For CEC it is Canadian experience with more scrutiny. For FSW it is still one year of outside Canada experience in the same profession.
So unless you meet at least one of these program's requirements, any CRS score is irrelevant. Hope that helps.
