KYF or grind.
Not sure why you created 2 exactly the same topics. But here's your answer.
There's 1 way to get perks without grinding bp and that's "Shrine of secrets", a rotation of 4 random perks that refresh each week, but it's random so there's no guarantee you'll get the perks you want.
Other way is obviously grinding bp.
Just play a killer with BBQ and bp offerings, you can easily get over 50k per match if you get all 4 stacks on your BBQ perk.
If you prefer survivor, get a we're gonna live forever perk.
But I assume you don't have either of these hence making this topic.
