PBD & Farting (serious)

Made the switch about 5 weeks ago for general health & longevity reasons and I feel great, but my farting is kind of out of control.

I know Dr Greger's book says there's not a link and dairy/meat gives just as much gas, but I've definitely seen a significant increase in how gassy I am. Which says a lot because I've always been pretty gassy. Used to wake the girlfriend up from farting so loud in my sleep, and almost suffocated us both in the bed of a truck one night with a topper on it.

Is there anything I can do? Any natural-ish fart suppressants, or foods I should avoid more, or not heat/cook as much or heat/cook more?

Typical days diet is a smoothie in the morning (banana/soy milk/berries/frozen greens/peanut butter), mid-morning apple, peanut butter & jelly + rice/soup leftovers for lunch, salad when I get home from work (spinach/cucumber/carrots/tomatoes) or carrots & hummus, then some combo of brown rice/beans/veggies in soup or corn tortilla form for dinner. Supplement with dried fruit (apples/raisins) and granola/fig bars throughout the day as necessary. Usually do a scoop of powdered protein (pea/rice/hemp) in water at some point too, since I bike/run/lift 6 days a week, but I'm farting like crazy regardless of if/when I take that.
