Same PlayerId because CPU Serial is 0000000000000000

[GrexAut]

Have problem with Rock 4SE, that CPU Serial is 0000000000000000 in output of /proc/cpuinfo

I read that playerId will be generated with output of cat /proc/cpuinfo |grep Serial|awk '{print $3 }'
I created image and duplicated SD card, deleted also files in player2/config/, also tried to change playerId in config file, but it they have still the same playerId.
