Is there any possible way to run DTS sound effect for headphones in linux?
Yesn’t. Look at HeSuVi and their process of making your own HRTF profiles. Once you’ll get impulse files you can use them with pipewire, they have a preset designed specifically for HeSuVi profiles.
It’s a lengthy process but the end result is roughly the same as with DTS Sound Unbound

Ugh, Sourceforge…
Take a look at easyeffects
have you tried EasyEffects?
This app is a godsend.
A bit OT: I recommend this loudness equalization preset: https://github.com/Digitalone1/EasyEffects-Presets
The audio stack for Windows and Linux are very different. As far as I’m aware it’s not possible. Anecdotally I’ve found that these applications are pretty useless anyways, if you play any modern competitive shooter it will have its own HRTF audio processing engine that works better anyways. I know CS2 and Valorant do. It’s not possible to get more accurate audio unless you know the actual position of the enemies which these programs do not.
Other than that good headphones with good imaging really helps. I.e. not typical gaming headphones.
Not DTS but I tried this pipewire filter some time ago and it works pretty well.
