How do we toggle GPU preprocessing?

[09/17/2023-00:43:46] [I] Average PreProcess Time: 15.7913 ms
[09/17/2023-00:43:46] [I] Average PfeInfer Time: 9.98707 ms
[09/17/2023-00:43:46] [I] Average ScatterInfer Time: 0.410112 ms
[09/17/2023-00:43:46] [I] Average RpnInfer Time: 18.2958 ms
[09/17/2023-00:43:46] [I] Average PostProcess Time: 3.27232 ms

These are my times as seen above. Based on the times, it seems like the CPU is handling preprocessed. How do I ensure the GPU is handling the preprocessing?
