Yes. If your monitor supports 144Hz, then you can also use lower refresh rate settings like 120Hz, 100Hz or 60Hz.
But why would you want to?

Cuz like i say most games I test on high setting or max run on 1440p between 75-110hz so is better to set 100hz for example in game that's run around 110fps or 75hz in game that on my gpu run 80fps isn't it?It's not be good if I have 80fps on 144hz or i missing something?

There's no benefit in doing that.

Why?Can you explain more please?I was think is not good idea play 80-100 fps on 144hz without gsync or freesync.

There's no benefit in lowering refresh rate to make it closer to framerate.
What exactly was your idea behind it?

If framerate is below 100fps, then there's no difference, if you set refresh rate to 100Hz or 144Hz. Without gsync or freesync - framerate and refresh rate will be out of sync anyway.

I'm new to pc that's why asking I was think of fps be around for example 80 is better set up monitor refresh rate to 75 with or without adaptive sync.fps be closer to refresh rate them when I keep them on 144hz what cousin tearing isn't?Or maybe is even pointless changing my monitor from 60hz to 144?Only reason my old one is 4 k so when I play 1440p is not realy native resolution btw🙁

Just set refresh rate to maximum available and don't worry about that. Also change vsync to adaptive in Nvidia control panel.

Screen tearing, when fps is below refresh rate, isn't that noticeable.
It becomes a problem, when fps is much higher than refresh rate.
