The Gallium dri driver i915 22.3.0 also at my laptop is working and stops the flickering problem. Unfortunately it still is not supported and also has issues. Specially with shaders it is not compatible with classic i915. Less shaders are compiled without errors and also there is no fallback (which works at classic i915 but can be very slow).
