Thanks, the issue is that we haven't released a new version in a while, and you read main's README while using a different version. Here's a link for the latest released version: https://github.com/Shopify/erb_lint/blob/v0.7.0/README.md#disable-rule-at-offense-level

Both are supported since #385:

erb_lint/lib/erb_lint/utils/inline_configs.rb

Lines 6 to 12 in 52cbaae

	def self.rule_disable_comment_for_lines?(rule, lines)
	lines.match?(/# erb_?lint:disable (?<rules>.*#{rule}).*/)
	end
	def self.disabled_rules(line)
	line.match(/# erb_?lint:disable (?<rules>.*) %>/)&.named_captures&.fetch("rules")
	end

Thanks, makes sense! I would love a version bump so no one else hits this 👍
