Disable case insensitive on command line

It is a common feature also on vim but I want to turn it off.

I have those:

o.ignorecase       = true       -- Search ignore case
o.smartcase        = true       -- Search ignore case unless search contains an uppercase
o.infercase        = true       -- Adjust case in insert completion mode

But i want that is disable only when I digit a command, there is a plugin or something for that?

Add \C (uppercase ā€œCā€) to the command
