for k, v in pairs(BattlefieldMapFrame.dataProviders) do
    if k.Label then
        local ft = { k.Label.Name:GetFont() }
        k.Label.Name:SetFont(ft[1], ft[2] * 0.5, ft[3])
        
        local ft = { k.Label.Description:GetFont() }
        k.Label.Description:SetFont(ft[1], ft[2] * 0.5, ft[3])
    end
end

I may add a scale modifier in the EFBM addon in next version. Since they are created in the EBFM.
