SKEW_ALLOWANCE = Duration.duration(5, TimeUnit.MINUTES) ability to tweek the time duration

A customer does:

upon calling the OIDC /token end point, and after passing the header client_assertion_type - jwt-bearer
client_assertion - has signed JWT, where exp as current time.
In this case the token end point is getting executed.It looks the FR is having exp check till exp+5 min.
Because the JWT which are sending is valid for almost 5 min.Can you please let us know if there is any setting to reduce it
Customer wants the ability to reduce that 5 minute time that is unfortunately hardcoded in the JwtClaimsValidationHandler.java file as:

private static final Duration SKEW_ALLOWANCE = Duration.duration(5, TimeUnit.MINUTES);

    private boolean isExpired()

{         return claimsSet.getExpirationTime().getTime()                 <= (Time.currentTimeMillis() - SKEW_ALLOWANCE.to(MILLISECONDS));     }
