Sorry, ProfileCMMType is not writable

[osgf]

Hi everyone.
I am new to this field, so I apologize in advance for the questions.
When I try to make changes to the following lines of the iPhone photo I see the message: Sorry,**, is not writable
ProfileCMMType   
ProfileVersion     
ProfileClass   
ColorSpaceData         
ProfileConnectionSpace       
ProfileDateTime   
ProfileFileSignature     
PrimaryPlatform     
CMMFlags   
DeviceManufacturer     
DeviceModel   
DeviceAttributes   
RenderingIntent   
ConnectionSpaceIlluminant 
ProfileCreator     
ProfileID 
ProfileDescription   
ProfileCopyright   
MediaWhitePoint 
RedMatrixColumn 
GreenMatrixColumn 
BlueMatrixColumn
RedTRC
ChromaticAdaptation
BlueTRC
GreenTRC
Also, I cannot transfer these lines from one file to another. Tell me where I can learn more about why this information is not rewritable?
Thanks

Those tags appear to be ICC Profile tags for the most part.  See the details at the top of that page.

See this example for how to copy it as a block.

It helps to include the group names (-G (-groupNames) option) and duplicates (-a (-duplicates) option) to figure out the groups that the tags belong to (see FAQ #3).  Then you can look under those group headings on the Tag Names page.

Thank you very much for your answer.
Please tell me how to remove a tag: JFIFVersion:1.01
If I enter the command:

exiftool -JFIFVersion= dsх.img

I am getting the following response:

Warning: Sorry, JFIFVersion is not writable
Nothing to do.

Thanks!!!

If you look on the JFIF tag page, you will see that the JFIFVersion tag is not writable, so it can't be removed.  It's a required part of the JFIF group.

You can remove the entire JFIF block with this command, but that will remove the other tags mentioned on that page
exiftool -JFIF:All= /path/to/files/

You help me incredibly. Thank you !!!!!

Let me ask one more question.
There is a Tag in the donor file: Flash. The recipient file has a Tag: Flashmode.
Question: How to change the name from the Tag from Flashmode to Flash in the recipient file?

I'm not sure I understand.  What is the output of
exiftool -G0 -a -s -*flash* File.jpg
