Change default on enter behaviour

How can I change default on enter behaviour. I can press ctl-t to open file in new tab, but I want to make enter open file in new tab. It it possible to configure plugin like this?

let g:rnvimr_action = {
            \ '<CR>': 'NvimEdit tabedit'
            \ }

:h rnvimr_action for detail

update the repo and

let g:rnvimr_action = {
            \ '<CR>': 'NvimEdit drop'
            \ }
