I’m not a bike mechanic, so take this with a grain of salt.

With my small sample size, I have found that it is easier to set up a nine speed drivetrain (double crankset) so that trimming is unnecessary; remember that with those two extra gears in an 11 speed cassette, your chain can travel to further extremes and make it more likely to rub on the front derailer – which necessitates trimming.

You’ve got three potential solutions: you can try to avoid cross-chaining, you can buy an electronic drivetrain which will automatically trim for you, or you can just trim the front derailleur yourself – which will become second nature after a while.

And by the way: you do not adjust the cassette to eliminate front derailer rub. Cassettes are not adjustable.
