Spidev @ Khadas vim3

Hello to the community,

At Khadas Vim3 (CoreELEC 19.3), i want to activate SPI / spidev by dtb overlay:
mount -o remount,rw /flash
fdtput -t s /flash/dtb.img /soc/cbus@ffd00000/spi@13000/spidev@0 status “okay”
fdtput -t s /flash/dtb.img /soc/cbus@ffd00000/spi@13000 status “okay”,
but the proposed method does not work:
fdtput -t s /flash/dtb.img /soc/cbus@ffd00000/spi@13000/spidev@0 status “okay”
Error at ‘/soc/cbus@ffd00000/spi@13000/spidev@0’: FDT_ERR_NOTFOUND

Is there any other possible way, or do I have to recompile kernel and/or dtb?

Thanks,
Nil
