Seurat V5 on MERFISH data without hdf5r files

I am planning to use Seurat V5 on a MERFISH dataset. The tutorial uses LoadVizgen function to read the files. However, I don't have hdf5r files from segmentation. Therefore, I won't be able to use LoadVizgen. I can read the data using ReadVizgen but it results in a plain list instead of a Seurat object. Any idea on how to read MERFISH data without segmentation information into a Seurat object?

To load Vizgen this workflow could help make Seurat objects
