nVAppAppApp - workaround NVIDIA DLSS4 whitelisting
<# Workaround for NVIDIA's DLSS4 whitelisting
-------- WHAT IS THE BACKSTORY? --------
DLSS4 was launched alongside the RTX 5000 series and comprise several new and interesting
features, f.e. additional presets for Super Resolution, using a newer Transformer model.
Arguably these features increase image quality significantly. To various degrees these
features are also available for older RTX cards, and older games using DLSS3/2.

Verifiers SHOULD NOT impose other composition rules (e.g., requiring mixtures of different character types or prohibiting consecutively repeated characters) for memorized secrets. Verifiers SHOULD NOT require memorized secrets to be changed arbitrarily (e.g., periodically).However, verifiers SHALL force a change if there is evidence of compromise of the authenticator.
