Resharper - keep named parameters when doing code cleanup

In ReSharper 2018.1

There are two relevant steps. You will likely want to do both, but it depends on how you want ReSharper configured.

First, in Resharper -> Options -> Code Inspection -> Inspection Severity, disable the "Use preferred argument style for literal values" code style. (For bools, "[..] for literal values" is the relevant setting, though I chose to disable all of them.)

This setting is also linked to the ReSharper -> Options -> Code Editing -> Code Style -> Arguments settings, so these should now be automatically changed to "Do not show" instead of "Hint":

Second, the default ReSharper Code Cleanup profile cannot be used due to the "Apply arguments style (named vs. positional)" - this option must be disabled in your code cleanup profile.

Although you can achieve it by doing what @EricWalker said, I want to propose another option.

You can start up the ReSharper options, look for Inspection Severity then go to Redundant explicit argument name specification and change this to do not show. This way you won't lose all the other good cleanups (like removing full name qualifiers) that remove redundant code offers.
