Is there a way to make sure the working Fedora 32 kernel is not remove when I upgrade from Fedora 33 to Fedora 34?

Please see

How can I change the number of kernels retained when updating in Fedora?

Edit the file /etc/dnf/dnf.conf, changing the numeric value in installonly_limit=3 to a number of your choice. Be aware that if you increase the number too high then you run the risk of filling up the /boot partition.
