Azure VM with alwayson AGs - expand data disk

I have a three nodes SQL Server Alwayson cluster on Azure VM. I need to expand the data disk on all three nodes. The disk is a stripe disk build during VM configuration. Based on this: https://learn.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/storage-configuration?tabs=windows2016#existing-vms I should exted the disk following instruction. But in my environment Azure prevent me doing this as the storage is part of an HA solution. How can I expand the disk without dismounting the HA solution?
