How To Make MoN Less Pulpy?

I am planning to run The Masks of Nyarlathotep at some point. I am looking to avoid the more pulpy elements and themes, and run it as more of a "traditional" Lovecraftian adventure.

I am looking at both minimising pulp rules (which I'll somehow have to tone down the lethality to do), and minimising pulp themes (which I don't have as much experience with).

Arguably, I should be running another campaign, but I'm looking to do what I can with MoN.

Any feedback would be much appreciated, thanks in advance!

Edit: I'm not experienced enough to know which pulp themes and narrative elements are present, so my question should've been: "What are the pulp themes and narrative elements in MoN, and how can I reduce them?"
