That's a super brutal gear for climbing like that. That's like, high 70s gear inches, no? That's approaching the high end of my gearing on my 1x11 rig.
Here in the LA mountains my ss gravel bike is geared at about 55 gear inches and even then it's too tough much of the time. I did only own one bike for about 3 years, a ss 29r mtb, and I just geared for the climbs at 32x20--that's about 46 gear inches--still some walking involved on our super steep trails and fire roads.
I'd seriously consider going significantly smaller in the front if you're gonna be climbing like that. You don't wanna injure yourself. Heck, maybe try as low as 42. Then you can play around with going up or down a bit with swapping out your rear cogs. I have 17t, 18t, and 19t that I swap out from time to time depending on where I'll be riding.
