I found something like this, is that what i need?

hooksecurefunc(getmetatable(PlayerFrameHealthBar).__index, "Show", function(bar, ...)
        if bar:GetParent().healthbar then 
            if bar.styled == nil then
        bar:SetStatusBarTexture("Interface\\AddOns\\EVUI\\FrameBackground")
        bar:GetStatusBarTexture():SetHorizTile(true)
        bar.styled = true
            end 
        end 
end)
