I tried the 6.4.0-1.1 kernel and it achieves package c8.
But, the power usage by the Realtek driver has greatly increased under 6.4. Using "top" with each kernel booted for a similar amount of time, 6.2 has cpu usage for irq/154-rtw88_pci of 0:02:92 whilst under 6.4 cpu usage for irq/155-rtw88_pci was 0:24:10.
