### Description

Cannot create networks without peering to the vWAN hub in subscription vending when the network is defined under additional networks.

There is a parameter to control peering (peerToHubNetwork) in additional networks, but the network is always peered regardless of its value. It does not matter whether an alternate hub exists or if it should peer to the main hub.

The peering is triggered here and does not respect the peerToHubNetwork parameter:

module createAdditionalLzVirtualWanConnection 'hubVirtualNetworkConnections.bicep' = [
for (vnet, i) in additionalVirtualNetworks: if (virtualNetworkEnabled && !empty(additionalVirtualNetworks) && (!empty(vnet.?alternativeVwanHubResourceId ?? '') || !empty(virtualHubResourceIdChecked))) {
dependsOn: [
createResourceGroupForAdditionalLzNetworking
createAdditionalVnets
]
