This answer is summarized below.
MBR partition a 16 GB or larger flash drive to contain a FAT32 volume and an ExFAT volume.
Copy all the fichiers, except sources/install.wim, depuis le mounted Windows ISO fichier vers le FAT32 volume sur le flash drive.
Copy sources/install.wim depuis le mounted Windows ISO fichier vers le ExFAT volume sur le flash drive.
Boot depuis le flash drive and enter a command to split the install.wim sur le ExFAT volume to two fichiers placed sur le FAT32 volume.
The result is an USB flash drive which can be used to installer Windows 11.
The steps are given next.

Entrez the commands below to copy the fichiers depuis le mounted ISO vers le flash drive. Note: Depuis the install.wim fichier is very large, the cp command can take a while to complete.
rsync -r -t --exclude=sources/install.wim . /Volumes/MYFAT32
cp sources/install.wim /Volumes/MyExFAT
Entrez the commands below to unmount the Windows 11 ISO fichier.
cd ~
hdiutil detach /Volumes/CCCOMA_X64FRE_EN-US_DV9
Entrez the command below to eject the flash drive. Afterwards, vous pouvez supprimez le flash drive.

Using the ordinateur where Windows is to be installé, UEFI boot depuis le flash drive. Vous devriez get a window similar vers le one shown below. Vous pouvez ignore the contents of this window.
-
Appuyez sur the shift+F10 clé combination to open Invite de commandes window.
Entrez the command below. From the output, determine the drive letters for the MYFAT32 and MyExFAT volumes. Dans mon cas, the was C and D respectively. If your letters are different, the make the appropriate substitutions for c:\ and d:\ when entering the dism command given below.
echo list volume | diskpart
Entrez the command below to créer the install.swm and install2.swm fichiers dans le c:\sources dossier. Note: This command will take a while to complete.
