Fedora 34 not going in sleep state cleanly

I have installed Fedora 34 on CHUWI CoreBox X Intel Core i7 | Win10 | Powerful mini PC | 8GB RAM+256GB SSD.
After 5 minutes of inactivity, CoreBox goes in sleep mode. In windows no issue, in Fedora, screen became black but the box is still working and I can gain access into it with ssh
Do u think this cab be a solution:

RUB_CMDLINE_LINUX_DEFAULT=“quiet splash acpi=force apm=power_off”
