TensorRT 6.0 Dynamic shapes - SSD

trying to apply dynamic shapes to SSD network I’ve found out that not all the plugins support this feature:
Normalize plugin does not support the required IPluginV2DynamicExt/IPluginV2Ext interfaces. ([E] [TRT] conv4_3_norm: PluginV2Layer must be V2Ext or V2IOExt or V2DynamicExt when there is no implicit batch dimension)
Permute plugin throws an exception while trying to parse ssd.prototxt

Could you provide a list of all the supported/not supported plugins?
Could you explain how to use dynamic shapes with SSD?
