How to delete a specific warning gcc

i have a specific warning that i would like to delete/ hide and then enable it just after. Do you have any idea how can i do that without deleting all the other warnings?

this is the warning i am getting

warning: enumeration value 'EtatCCSortie' not handled in switch [-Wswitch]

and i dont need to actually use that state in the switch (it's a state machine). I have a way to noy get this warning anymore which is by adding the state to the switch like this:

while (etatsImprimanteCasImpressionPeriodique != EtatIPSortie)
{
         switch (etatsImprimanteCasChangementCartouche)
         {
               ....
               case EtatCCSortie:
               break;

But i don't have to add it because it will never execute (while !=). that's why i am looking for a way to unable this specific warning and then enable it just after this switch.

Ps:i am aware of the importance of warnings and i only need a way to delete it.

Using:

#pragma GCC diagnostic ignored "-W<replace_this_with_the_warning>"

Use diagnostic pragmas:

enum somenum {
    EtatIPSortie,
    EtatCCSortie,
};
int etatsImprimanteCasImpressionPeriodique;
enum somenum etatsImprimanteCasChangementCartouche;

void func() {
    while (etatsImprimanteCasImpressionPeriodique != EtatIPSortie)
    {
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wswitch"
            switch (etatsImprimanteCasChangementCartouche)
            {
                case EtatCCSortie:
                break;
            }
#pragma GCC diagnostic pop
    }
}
