Plymouth config after minimal ISO installation

Hello everyone
I installed Rocky 9 using the minimal ISO.
To get the graphical boot I edited /boot/loader/entries/*.conf adding “rhgb quiet”.
It works, but every time I install a new kernel, I need to edit the new file in /boot/loader/entries/.
Is there a better way to get the graphical boot working?
I tried editing grubenv using grub2-editenv, and /etc/default/grub, but still no luck.
Thanks in advance.

Did you run sudo grub2-mkconfig -o /boot/grub2/grub.cfg --update-bls-cmdline after editting the /etc/default/grub file?

No I didn’t.
I am going to do it right now, I will see if this works when a new kernel update happens.
Thank you.
