You can achieve this by setting the options pageLength of DT: Example rmd:

---
title: "Untitled"
author: "TarJae"
date: "5 2 2021"
output: html_document
---

chunk 1

knitr::opts_chunk$set(echo = TRUE)
library(DT)
options(DT.options = list(pageLength = 100, language = list(search = 'Filter:')))

chunk 2:

datatable(mtcars)
