Odd issue, as the start g-code entails the exact same value.
There are a few ways to achieve what you´re looking for, but the most straightforward is to edit the printer start g-code to include the k value of 0.02.
If you choose this solution, check if the setting is effective. E.g. you can follow @vladimir.minkov suggestion:
Why is K Value stored on the Printer and Flow Rate on the Filament?
Also, the thread entails other methods for adding the k-value sch, such as editing the JSON file.
