Update = After verifying ownership and completing troubleshooting, a DELL agent setup service.
My x17-R2 arrived today but the Cherry MX keyboard is malfunctioning since the first start up. The (ESC, ` , Tab, Caps) column and (F1,1,q,a,z) column are not working though light is on. After restart several times the problem is gone, but later appeared again with only the second column malfunctioning. Just exactly like what this guy described.  I hope Dell can make the technical team to work on a x17 R2 windows 11 Cherry MX firmware utilities as soon as possible since this problem can be solved but not solved for like half an year, like it's solved back in September 2021.
