Do you see widespread political agitation to stop fighting ? Do you see defense contractors deliberately leaving orders unfilled ? Is there sabotage of vehicles and munitions ?
We are probably quibbling over definitions, but without the above, there is clear evidence of the desire to not be Russian.
Now, no one can doubt this is changing over time:
New data from Ukraine show the public favors ending the war with Russia through negotiations, as support for fighting until victory has plummeted.

With an increase in "Ukraine should seek to negotiate an ending to the war as soon as possible" this points to war weariness- but this is not the same as surrender. I take (collective) desire to not fight = surrender.
Quantitatively, sure, but the presence of draft dodgers alone doesnt imply anything other than the human nature to not get killed. We are agreeing in principle and disagreeing to the extent of "wanting to fight".
Once we see several of the following, you can be sure the wheels have fallen off the UKR war effort:
- polling indicating the desire to end the war no matter what
- mass protests
- domestic war production suffering from strikes or other logistic disruptions
- widespread, continued RU advances with lower casualty rates
