Shimano 105 FD-R7000-F front dereailleur chain rub Recently purchased a new Cube Attain GTC 2020 road bike, it came with :

Front Derailleur -  Shimano 105 FD-R7000, 31.8mm Clamp
Rear Derailleur -   Shimano 105 RD-R7000-DGS, 11-Speed
Brake System - Shimano 105 BR-R7070, Hydr. Disc Brake, Flat Mount
Crankset - Shimano FC-RS510, 50x34T

All seems good, however I've noticed the chain is rubbing on the front derailleur when using the 50T ring on the first 5 gears.
This I take it is due to cross chaining, i know it's not advised to use the opposite sides of the cassette but are they all like this ?

Note : I don't get any chain noise or rub when using the 34T ring in any of the 11 gears on the cassette.

So my question is this - can the front derailleur be adjusted to eliminate the chain rub on the 50T ? or will this effect the indexing on the 34T ring ? 

I've read through the PDF from Shimano and they say chain noise is normal, really? can you only use the whole range on one chain ring ?

I'm aware of the high and low screw adjustment but don't want to tweak anything if it's going to throw the indexing out of alignment on the 34T ring.
I don't know about the R7000 in particular, but your FD most likely has a 'Trim' function to help with this.  This is usually activated by light/half click as if you were going to the small ring but not actually doing so.

I'd say if you are getting rub on the lowest 5 gears in the big ring, but no rub at all on the small ring your FD position is slightly out.  It is common to have rub in the 2-3 gears at the extreme ends (small ring high gears, big ring low gears) of the gear range.
