Description

selecting Default gateway as NONE should remove the default route from routing table.

making default GW as "NONE" will not remove the default route.
Mark Gateway as "Down" does not remove the default route.

disabling the interface or using the command route delete 0.0.0.0/0 [gateway ip] are the only way to remove it.

selecting Default gateway as NONE (GUI) should take an effect to remove the default route from the routing table.

removing the default gateway, if set to 'none', may result in the removal of the route of dynamic routing protocols
https://github.com/pfsense/pfsense/blob/master/src/etc/inc/gwlb.inc#L1115-L1117:

    if ($gwdefault == "-") {
        // 'none', dont set the default gateway, useful if routes are managed by frr/bgp/ospf or similar
        return;
    }
