Basic question about finding mRNA sequence in transcriptome
Basically you want to know the VHL Gene expression in that 10x dataset. They have provided the barcode, matrix and feature files on GEO GSE131685 as Supplementary file. You could use those files and get the gene expression matrix as described on 10x website.
library(Matrix)

matrix_dir = &quot;/opt/sample345/outs/filtered_feature_bc_matrix/&quot;
barcode.path &lt;- paste0(matrix_dir, &quot;barcodes.tsv.gz&quot;)
features.path &lt;- paste0(matrix_dir, &quot;features.tsv.gz&quot;)
matrix.path &lt;- paste0(matrix_dir, &quot;matrix.mtx.gz&quot;)

mat &lt;- readMM(file = matrix.path)

feature.names = read.delim(features.path, 
                           header = FALSE,
                           stringsAsFactors = FALSE)

barcode.names = read.delim(barcode.path, 
                           header = FALSE,
                           stringsAsFactors = FALSE)

colnames(mat) = barcode.names$V1
rownames(mat) = feature.names$V1

This mat can be further loaded into Seurat for any downstream analysis. All this can be done on a laptop.
If you want to re-quantify the gene expression for whatever the reason, you need to re-run the cellRanger pipeline using GTF of your interest (it needs some preparation), which may not work on your laptop. It requires large memory and long running times, ideally to submit as job on cluster.
