changing the crtime in bash - bash

Question

I want to change crtime properties in bash.
First, I tried to check the crtime as following command.
stat test
And next, I changed the timestamp.
touch -t '200001010101.11' test
But I realized that if the crtime is already past than the date I wrote, then it can't be changed.
So I want to know how to specify the crtime even it is already past.

Edit:
According to This answer to a similar question, you may be able to use debugfs -w -R 'set_inode_field ...' to change inode fields, though this does require unmounting.
man debugfs shows us the following available commmand:
set_inode_field filespec field value
Modify the inode specified by filespec so that the inode field field has value value. The list of valid inode fields which can be set via this command can be displayed by using the command:
set_inode_field -l Also available as sif.
You can try the following to verify the inode number and name of the crtime field:
stat -c %i test
debugfs -R 'stat <your-inode-number>' /dev/sdb1
and additionally df -Th to find the /dev path of your filesystem (e.g. /dev/sdb1)
Followed by:
umount /dev/sdb1
debugfs -w -R 'set_inode_field <your-inode-number> crtime 200001010101.11' /dev/sdb1
Note: In the above commands, inode numbers must be indicated with <> brackets as shown. Additionally, as described here it may be necessary to flush the inode cache with echo 2 > /proc/sys/vm/drop_caches
Original answer:
You might try birthtime_touch:
birthtime_touch is a simple command line tool that works similar to
touch, but changes a file's creation time (its "birth time") instead
of its access and modification times.
From the birthtime_touch Github page, which also notes why this is not a trivial thing to accomplish:
birthtime_touch currently only runs on Mac OS X. The minimum required
version is Mac OS X 10.6. birthtime_touch is known to work for files
that are stored on HFS+ and MS-DOS filesystems.
The main problem why birthtime_touch does not work on all systems and
for all filesystems, is that not all filesystems store a file's
creation time, and for those that actually do store the creation time
there is no standardized API to access/change that information.
This page has more details about the reasons why we haven't yet seen support for this feature.
Beyond this tool, it might be worth looking at the source on Github to see how it's accomplished and whether or not it might be portable to Unix/Linux. And beyond that, I imagine it would be necessary to write low level code to expose those aspects of the filesystems that crtime would be stored.
