HAL lint check design_info file

Hi, I am trying to turn off some checking rules in the design_info file. I tried the example given by reference manual

INFNOT {pattern = "*unused_*"} off;

and it does not work. I also tried

INFNOT {pattern = *unused_*} off;

but it seems that it exempts the whole file from INFNOT rule instead of lines containing that pattern.

Anyone has an idea what's the correct way to exempt rule checking based on pattern?
