How to manualy change/save AudioProcessorValueTreeState?

Hello,
I mean, such situation:
I have normal knobs (Slider) which behave normally - changing parameters by dragging. But I also have some additional graphic panel to remote the same parameters. In class of that graphic panel I also update knob value by calling myKnob.setValue(valueToSet, dontSendNotification).
And in that case parameters from AudioProcessorValueTreeState are not saved (when I close my plugin, and open again, the old values back).

When I set knob using sendNotification, everything works perfect, but if I want to avoid sendNotification then how to save parameters manualy?

For any help thanks in advance.
Best regards
