Why did my dd command change disk from ExFAT to UDF (Universal Disk Format)

I have a usb disk and I have format it to ExFAT on Mac. Then I run the command to create a bootable windows on Mac: sudo dd if=Win11_24H2_EnglishInternational_x64.iso of=/dev/disk4 bs=8m status=progress The command finishes successfully but the disk format is changed to UDF (Universal Disk Format) which is not recognised by windows installation. How can I keep the disk format no change? I want it to be stay as ExFAT.
