Can you use independent R and Python chunks in RMarkdown Kaggle Kernels? (without reticulate syntax, '$' operator)

I'd like to use the R Notebook shorthand described here in an RStudio blog post and here in the RMarkdown Guide which allows independently executable Python and R chunks in R Notebook documents. Is this possible to set up inside of a Kaggle kernel that uses RMarkdown?

I've tried the below so far in a fresh Kaggle kernel with no success:

{r setup, include = FALSE}    
    library(reticulate) 
    
    use_python('../../usr/bin/python3.5')

{python}
    import pandas # error: 'pandas/import unrecognized...etc'
