You might use std::typeidentity (C++20, but can be reimplemented for previous standard) to have a non-deduced context:

template 
void toggleFlag(Flags& targetFlags,
                std::typeidentity_t flagToSet,
                bool enabled)
{
    if (enabled)
        targetFlags |= flagToSet;
    else
        targetFlags &= ~flagToSet;
}
