This does the trick!🙂 With pak::pak(c("tidymodels/tune", "tidymodels/rsample#463")):

library(tidymodels) 

val_split <- initial_validation_split(mtcars) 
val_set <- validation_set(val_split) 

# fit_resamples() and tune_*() work with rsets
res <- fit_resamples(linear_reg(), mpg ~ ., resamples = val_set)
