Instead of modifying the htaccess.conf file, could you please try modifying the httpd-app.conf file of Magento?
<IfVersion < 2.3 >
Allow from all
<IfVersion >= 2.3>
Require all granted
You can modify the "Require all granted" configuration with the one you want to have. You can also add the configuration of the bots in the same file.
Let us know if you have any questions
