Then prove it has evolved past Adult Goku and Master Roshi’s level of IR, besides UI and MUI.
Adult Goku feat before UI: BoG arc, Goku’s body subconsciously predicted that Beerus was going to attack and moved out of the way before Beerus could attack. Goku was confused as to why that happened, Beerus explained to Goku that it was due to his fighting prowess allowing him to react instinctively.
Master Roshi’s feat: performed an instinctive reaction feat greater than Battle of God Goku’s feat with Beerus. Someone Goku has far surpassed is capable of reacting to Jiren who Goku is struggling with. His Instinctive reaction was stated by Whis to be similar, yet a Far Cry from Ultra instinct’s capabilities.
Prove Garou has surpassed those two very impressive feats which are a way below baseline Ultra Instinct.
If you bullshit your way out of this one you still have to prove Garou covers the gap between those two feats and UI. Then prove Garou covers the gaps between Goku improving UI sign over time, then another gap where Goku masters UI, then you will have to keep bullshitting your way past his UI improvement thanks to Goku’s training with Merus in the Moro Arc, BS your way past the UI that decimated Moro, who copied UI and other fighters, Then you have Granola arc where Goku incorporates UI into his Base and improves it further with his transformations. (Granola became the strongest in the universe, He first attacks Goku and Vegeta with a weaker clone that is faster than them, attacks them, attacks them at full strength. Then Gas comes along and becomes the strongest in the universe to surpass Granola’s speed and strength to attack) an improved version of MUI Allowed Goku to keep up with Granola’s clone’s attacks (the clone is stronger and faster than both Goku and Vegeta), Goku improves, beats up the clone gets distracted and gets taken out by a sneak attack. Later on he wakes up and further improves to surpass the clone, and the real deal to match another character named Gas who is faster than Granola.
There is no way you can get Garou above Master Roshi and it’s not even possible to bullshit your way into these layers of UI.
Don’t disappoint me
