The final version, that seems to be working:

TargetFrame:UnregisterEvent("UNIT_AURA")
FocusFrame:UnregisterEvent("UNIT_AURA")
 
local function ReleaseAllAuras(self)
    for obj in self.auraPools:EnumerateActive() do
        obj:Hide()
    end
 
    -- Cleanup
    self.auraPools:ReleaseAll()
 
    -- Revert to initial values
    self.auraRows, self.spellbarAnchor = 0, nil
 
    if self.spellbar then
        -- Reset anchor
        hooksecurefunc(self.spellbar, "SetPoint", function(spellBar, _, _, _, _, _, shouldIgnore)
            if not shouldIgnore then
                spellBar:ClearAllPoints()
 
                -- Default anchor on large frame with ToT shown
                spellBar:SetPoint("TOPLEFT", self, "BOTTOMLEFT", 43, -100, true)
            end
        end)
    end
end
 
hooksecurefunc(TargetFrame, "UpdateAuras", ReleaseAllAuras)
hooksecurefunc(FocusFrame, "UpdateAuras", ReleaseAllAuras)

UPDT: 43,-28 works the best for me.
