The version of python installed in my local gentoo installation is
localhost ~ # python3 --version
Python 3.9.9

therefore I changed  PYTHON_COMPAT=( python3_8 )  -> PYTHON_COMPAT=(
python3_9 )
What is wrong with changing PYTHON_COMPAT=( python3_8 )  -> PYTHON_COMPAT=(
python3_9 ) ?
I have tested confluent-kafka installed with python3_9 and i works !

Nevertheless I have followed your advice.
As far as I understood you I did the following steps:

1. Created the file /etc/portage/package.use/confluent-kafka:
dev-python/confluent-kafka PYTHON_TARGETS: -* python3_8

2. emerge  --autounmask-write dev-python/confluent-kafka

Autounmask changes successfully written.

 * IMPORTANT: config file '/etc/portage/package.use/grub' needs updating.
 * See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS
 * sections of the emerge man page to learn how to update config files.

3. etc-update
The following is the list of files which need updating, each
configuration file is followed by a list of possible replacement files.
1) /etc/portage/package.use/grub (1)
Please select a file to edit by entering the corresponding number.
              (don't use -3, -5, -7 or -9 if you're unsure what to do)
              (-1 to exit) (-3 to auto merge all files)
                           (-5 to auto-merge AND not use 'mv -i')
                           (-7 to discard all updates)
                           (-9 to discard all updates AND not use 'rm -i'):
-3
Replacing /etc/portage/package.use/grub with
/etc/portage/package.use/._cfg0000_grub
mv: overwrite '/etc/portage/package.use/grub'? yes
Exiting: Nothing left to do; exiting. :)

4. emerge  --autounmask-write dev-python/confluent-kafka
...
running install_scripts
 * Using python3.8 in global scope
 * python3_8: running distutils-r1_run_phase distutils-r1_python_install_all
>>> Completed installing dev-python/confluent-kafka-1.7.0 into

Now package dev-python/confluent-kafka with python 3.8 is installed

emerge --search confluent-kafka
  dev-python/confluent-kafka

Is this correct ?
