RPC context is not identifying gpu device

Development
#1

I am attempting to use aarch64-linux-gnu target with (CPU and Nvidia’s GPU on remote device). CPU is identified from RPC session but not the same for GPU.

ctx = remote.gpu()
print(ctx.exist)
False

ctx = remote.cpu()
print(ctx.exist)
True

ctx = remote.gpu(1)
print(ctx.exist)
False

ctx = remote.gpu(0)
print(ctx.exist)
False

#2

should we use remote.cuda() ?

Setup:
Remote machine: nvidia jetson agx xavier, linux-aarch64
Host: linux pc , x_86

I tried it gave following output
ctx = remote.cuda()
print(ctx.exist)
True

Is there any guide of using RPC to connect with gpu device
