Yes, I think so.

During my investigation, I learned about "lsinitramfs" and ran "lsinitramfs | 
grep modprobe" to see what there was.

In the broken, dracut-generated initramfs, there were only 4 or so files in /
etc/modprobe, and it did NOT include the nvidia ones.  

In the working initramfs, the list looks like what I have on my sytem:

$ sudo lsinitramfs /boot/initrd.img-6.10.12-amd64|grep modprobe
etc/modprobe.d
etc/modprobe.d/amd64-microcode-blacklist.conf
etc/modprobe.d/dkms.conf
etc/modprobe.d/intel-microcode-blacklist.conf
etc/modprobe.d/mdadm.conf
etc/modprobe.d/nvidia-blacklists-nouveau.conf
etc/modprobe.d/nvidia-options.conf
etc/modprobe.d/nvidia.conf
etc/nvidia/current/nvidia-modprobe.conf
usr/lib/modprobe.d
usr/lib/modprobe.d/aliases.conf
usr/lib/modprobe.d/fbdev-blacklist.conf
usr/lib/modprobe.d/systemd.conf
usr/sbin/modprobe
