chrome://flags/#temporary-unexpire-flags-m137 [Enabled]
Then you can set:
chrome://flags/#extension-manifest-v2-deprecation-warning [Disabled]
chrome://flags/#extension-manifest-v2-deprecation-disabled [Disabled]
chrome://flags/#extension-manifest-v2-deprecation-unsupported [Disabled]
chrome://flags/#allow-legacy-mv2-extensions [Enabled]
But this will be removed soon too, so save the data from your extensions!
