Reverting upgraded port after 'pkg clean' was run

[sir_dog]

I have a FreeBSD14 machine

FreeBSD dog 14.3-STABLE FreeBSD 14.3-STABLE stable/14-n272990-e1c985ccc335 GENERIC amd64

with NVIDIA graphics card. Recently I ran 'pkg update && pkg upgrade' and had nvidia-related ports upgraded to the latest version

nvidia-driver-580.119.02       NVidia graphics card binary drivers for hardware OpenGL rendering
nvidia-kmod-580.119.02.1403000 kmod part of NVidia graphics card binary drivers for hardware OpenGL rendering
nvidia-settings-580.119.02     Display Control Panel for X NVidia driver
nvidia-xconfig-580.119.02      Tool to manipulate X configuration files for the NVidia driver

Then I carelessly ran 'pkg clean' and rebooted the machine. After reboot all windows in the XFCE session started blinking, as well as indicators on the main panel. As I cleaned previous packages, I'm not able to forcibly install them anymore. And as far as I know they aren't kept on pkg-building servers after rebuild and update.
I tried to install old-school portdowngrade to reinstall them using ports tree, but it looks like it doesn't work anymore, shows the following error:

% portdowngrade x11/nvidia-kmod
Choose a revision from this list and run /usr/local/sbin/portdowngrade x11/nvidia-kmod revision
svn: E160013: '/ports/!svn/rvr/569609/head/x11/nvidia-kmod' path not found

Is there any way for me to find somewhere previous nvidia-* packages or revert the ports tree to the particular commit and reinstall them that way? After the recent 'pkg upgrade' X session has become unbearable.
