Is it safe to use Mojave's Boot Camp Assistant to remove a Windows 7 partition?

I have a Windows 7 Boot Camp partition that I want to remove. It was set up in Boot Camp in earlier versions of MacOS; however, I have since updated to Mojave and it seems that Boot Camp Assistant has updated, too. Its partition removal option only mentions "Remove Windows 10 or later version", suggesting it might not support removing earlier versions. Can that option still be used to safely remove the partition or should it be avoided?

Edit: per @Jean_JD's follow-up question, the results of running the diskutil list internal command:

/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                 Apple_APFS Container disk1         401.1 GB   disk0s2
   3:       Microsoft Basic Data BOOTCAMP                99.0 GB    disk0s3

/dev/disk1 (synthesized):

   2:                APFS Volume Preboot                 113.3 MB   disk1s2
   3:                APFS Volume Recovery                2.1 GB     disk1s3
   4:                APFS Volume VM                      1.1 GB     disk1s4

Solution 1:

Ok. Execute the terminal command :

diskutil erasevolume free space disk0s3

Then, I suppose you want add the free space to your Mac os x Container. If yes, execute :

diskutil ap resizecontainer disk1 0b

Then, to suppress Windows references at boot, you mount the EFI partition :

sudo diskutil mount disk0s1

Your password will be requiered and don't show up when you type it

Then you give the results of :

ls -l /Volumes/EFI/EFI

Normaly you have a Directory WINDOWS, so you delete it :

rm -r /Volumes/EFI/EFI/WINDOWS

And it's all ;-)
