Normalisation / SCTransform for SVG spatial analysis #9654

I have a 10x visium dataset within my seu object and I want to run Seurat::FindSpatiallyVariableFeatures on this data. It seems that this function first requires the data to be normalised with Seurat::SCTransform prior to calculation. Not doing so results in this error message:

Error in `object[[assay]]`:
! ‘SCT’ not found in this Seurat object

Is it possible to run FindSpatiallyVariableFeatures on data that is not normalised? Or on data that is normalised with an alternative normalisation method such as Seurat::NormalizeData for example?
