I find that with all modern bikes (bb sits below the wheel axles) it is absolutely beneficial to change or learn the proper manual technique.
It is not about pulling the bars but instead mainly thrusting forward and a little downward with your feet through your hips.
You need the right (not too low, not too high) bar height and it will feel natural with enough practice.
Pulling on the bars worked with 26“ bikes or BMX, it doesn’t any longer.
I struggled with the manual for years (more like decades), but I finally learned it on the bike with the longest chainstays I ever owned.
I now can do it pretty effortless for a minute or longer (if there’s a long enough road with a slope.
On narrow trails my hit rate is much lower, but I can lift the front wheel practically effortless for a couple of meters basically anywhere on long bikes, which increased my confidence in a lot of situations).
It was about technique and not geometry (in my case). Ryan Leech’s online course and the L-hint (your hip must make an L shaped movement while lifting the front wheel).
Before mastering this particular technique there where certain situations on long 29ers where I was more passenger than rider.
That said, benefits of long geometries can be enjoyed in most situations without much rider input.
I hope that doesn’t sound too haughty. It isn’t meant that way. I am in no way a pro rider.
Maybe it helps if you film yourself riding the bike to see potential for adjustment and unlock the full potential?
The 440mm chainstays will make a noticeable difference anyhow!
