// Modifies a subnet attribute. You can only modify one attribute at a time. Use

// * To modify a
// subnet on an Outpost rack, set both MapCustomerOwnedIpOnLaunch and
// CustomerOwnedIpv4Pool. These two parameters act as a single attribute.
//
// * To
// modify a subnet on an Outpost server, set either EnableLniAtDeviceIndex or
// DisableLniAtDeviceIndex.
