Yes you can prefetch your data while training the network in MATLAB if you have a GPU. While the GPU is working on the current mini-batch of data, the CPU can simultaneously prepare the next mini-batch, which helps reduce the time the GPU spends waiting for data.
To implement data prefetching in MATLAB, you can use the "backgroundDispatchEnable" property of the "miniBatchQueue" object. This property enables the loading and processing of data in the background while the GPU is training on the current batch.
You can refer to these documentations:

Check with this MATLAB Answer and discussion.
Try checking Parallel Pooling preferences in Home Tab, "Automatically create a parallel pool" option should be checked.
You can also start a parallel pool manually before calling train network by using "parpool" function.
