Tom,
This is the all knobs to the right syndrome. It just does not sink
into some minds that 100 watts is about the maximum that can be realized
from a typical automotive battery voltage of 13.8 volts without
running into unacceptable IMD regions.
I certainly don't know how to counter it.

Hello,
Actually ATU TUNE is configured per band. Is there any option to have it OFF
in all bands and not to be remembered?
Something like SPLT SV (yes/no) for the SPLIT mode. But I couldn´t find the
same for ATU TUNE.

Antenna tuners have their place---just not in my shack. That said, your tuner
is actually a band-pass filter whose performance as a filter is dependent on
what it's matching.
If you really need a high-pass filter to correct an issue, then I think that
you should use a purpose-built filter.
K3 remembers whether ATU is engaged or bypassed per ANT1/ANT2 per
band, and remembers L/C settings per band. You are asking it
specifically to return to bypass when you leave a band?
It's not like you have to do some complicated thing down in the menus.

There are three connections between the P3 and your K3. The necessary cables
are supplied.
1) A +12V cable connects between the P3 and the RCA +12V connector on the
back of the K3.
2) A short coaxial cable with BNC connectors connects to the IF OUT
connector on the KXV3 or KXV3A of your K3.
