I implemented this but then had to add some further lines based off something off twitter. Here's what I have in chromium:

youtube.com##+js(set, yt.config_.openPopupConfig.supportedPopups.adBlockMessageViewModel, false)

youtube.com##+js(set, Object.prototype.adBlocksFound, 0)

youtube.com##+js(set, ytplayer.config.args.raw_player_response.adPlacements, [])

youtube.com##+js(set, Object.prototype.hasAllowedInstreamAd, true)

www.youtube.com##.opened

www.youtube.com##tp-yt-paper-dialog.ytd-popup-container.style-scope > .ytd-popup-container.style-scope

||accounts.google.com/gsi/*$xhr,script,3p

##.ytp-endscreen-content

youtube.com##.ytp-scroll-min.ytp-pause-overlay

youtube.com##.ytp-ce-covering-shadow-top

youtube.com##.ytp-pause-overlay

youtube.com##.ytp-ce-covering-overlay

youtube.com##.ytp-ce-element

YMMV as always.
