Droppers make any bike better for trail riding. 1990 Rigid, 2000 Hardtail, or 2020 FS bike, Wide flat bar, drop bar, any of these will benefit.
The main issue is going to be if you have enough room to run one. How much seat post do you have exposed when the seat is all the way up?
Your bike is fine to ride on real trails. Put a 750mm bar and short on that and you will have a more capable bike than I what was riding in the late 90s on the same trails people are now riding modern FS bikes on.... I was just slower.
