Is it possible to disable the default keybindings?

I don't need 99% of them and some of them override my own/

I’d also be interested in an answer in case somebody knows.

Being new to the plugin, my biggest issue so far is Tab conflicting with UltiSnips. I’ve tried placing the following in Neovim’s init.vim, but it doesn’t work (I’m not even sure how to use g:riv_i_tab_user_cmd correctly).

Edit: I've managed to make Tab work with UltiSnips as well as disable Ctrl-E as riv’s leader. Here's the updated snippet.

let g:riv_global_leader = ''
let g:riv_ignored_nmaps = "<Tab>,<S-Tab>"
let g:riv_ignored_imaps = "<Tab>,<S-Tab>"
let g:riv_ignored_vmaps = "<Tab>,<S-Tab>"
let g:riv_i_tab_pum_next = 0
let g:riv_i_tab_user_cmd = "\<c-g>u\<c-r>=UltiSnipsExpandTrigger\<cr>"
