If you don’t want to use opencv converter, you can try to extract channel first, and then combine them with preferred order.

For example:

vxChannelExtractNode(graph, inputRGB, VX_CHANNEL_R, channelR)
vxChannelExtractNode(graph, inputRGB, VX_CHANNEL_G, channelG)
vxChannelExtractNode(graph, inputRGB, VX_CHANNEL_B, channelB)
vxChannelCombineNode(graph, channelB, channelG, channelR, NULL, outputBGR)

Following tutorial also use channel extract and channel combine. You can take a look.
