Have you tried using i915.enable_psr=0 instead of nomodeset?
Nomodeset is no more than a troubleshooting enabler, so that reconfiguration and/or data collection is facilitated. Most Intel GPUs from the past two decades or more require i915 kernel module for competent operation. Plasma and SDDM are too demanding to be used without KMS, which i915 provides, enabled. You should try ruling out SDDM by switching to a different DM. I use LightDM, TDM or XDM instead of SDDM. While disabling KMS might be required for performing certain fixup functions, it is highly unlikely ever to be a part of a favorable end result. So, when you try something other than making repairs or collecting data, nomodeset can't be part of the current /proc/cmdline.
AFAIK, Plasma simply won't run on any fallback driver, so either i915 needs to work, or you need to find what will, if such exists. That might be Xe. However, you might need to force it using the following: xe.force_probe=46d1 i915.force_probe=!46d1 (without nomodeset).
As I understand it, some low power models of Intel GPUs simply do not have support from any FOSS kernel module. I haven't seen any evidence that any Alder Lakes are among them, but one never knows what one doesn't know.....
BTW, a subsumes xxx when using G with inxi:I also recommend a separate option with inxi, regardless which are first used, when posting inxi output in public: --za. It suppresses extra data that doesn't usually need to be made public. The first z with initial parameters does more limited suppression.
