That double pole breaker could be replaced with a double pole GFCI breaker. If the circuit is currently mis-wired using two single pole breakers, replacing one of those with a GFCI breaker will not work due to the shared neutral, nor will two single GFCI breakers, only one double pole GFCI breaker can be used.
