My system is low on “/boot/efi” space, so can I safely remove these language folders?

On a dual boot I run out of /boot/efi space because Microsoft Windows really made a small partition:

$Volume = Get-Volume | Where-Object {$_.FileSystemType -eq "FAT32" -and $_.DriveType -eq "Fixed"}
$SystemDisk = Get-Disk | Where-Object {$_.IsSystem -eq $true}
$SystemPartition = Get-Partition -DiskNumber $SystemDisk.DiskNumber | Where-Object {$_.IsSystem -eq $true}  
$SystemVolume = $Volume | Where-Object {$_.UniqueId -match $SystemPartition.Guid}

The $SystemVolume is reported as:

DriveLetter FriendlyName FileSystemType DriveType HealthStatus OperationalStatus SizeRemaining  Size
----------- ------------ -------------- --------- ------------ ----------------- -------------  ----
                         FAT32          Fixed     Healthy      OK                     58.57 MB 96 MB

If I then find all mui files:

MuiFiles = Get-ChildItem -LiteralPath $SystemVolume.path -Recurse | Where-Object {$_.Name -match "mui" }

I see at lot like these:

Verzeichnis: \?Volume{344cdef3-e644-4ef7-a3f6-6ec0a16c0be4}EFIMicrosoftBootpl-PL


Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----

-a----          4/1/2024   9:22 AM          47008 memtest.efi.mui

Not only for Poland but for effectively every language in the world.

I don’t need these and wonder if can safely delete these except for a few I might need.
