MATLAB: Bioinfomatics toolbox hardware optmization

Bioinformatics ToolboxgpuParallel Computing Toolbox

Hi, I am planning to use Matlabs Bioinfomatics toolbox to do RNA-seq analysis from quite a number of biological samples.
The RNA-seq library that I have used has 30 million reads which produces a FASTAQ result of about 3-4GB per sample. Currently the PC I am running Matlab on is a i7 9750H Laptop with 16GB of RAM and a RTX 2070 GPU. For anyone who has worked with the Matlab Bioinfomatics toolbox before, may I know if the low level code has been hardware optmized to run with GPU acceleration? I would need to align 30 million sequences to my reference genome along with QC analysis for each sequence. Would this process be possible to be sped up with GPU? Also, would 16GB of RAM be enough for such a process?
I would appreciate any help and advice I can get on this as I am very new to Matlab itself and I am quite unsure of how the low level code interfaces with my Machine's hardware? i.e. OpenGL, CUDA, etc…

The Bioinformatics Toolbox does not have any native alignment functions; for now it relies on Bowtie2, which is available as a support package. To my knowledge Bowtie2 is not optimized to run on GPUs. None of the Bioinformatics Toolbox functions have been tested with or optimized for gpuArrays, but some may benefit from optimizations on the native data types like double.
However, bowtie2 does support multiple threads, and does not have particularly high memory requirement, so 16GB should be enough.
