Quantization in Post Relay TVM

Hello, I was wondering if there are options for quantization in post Relay TVM. To be able to build support and research for custom accelerators, integer support through quantization is needed. In the old VTA flow, relay.quantize was used to quantize to int8, which the VTA hardware was able to compute with (floating point is typically not used on these custom hardware accelerators). Are there any plans to create a relax.quantize, and if not, what options do people have if they want to explore TVM with custom accelerators. I know MLC LLM has some quantization built on top of relax TVM but that is only for weight storage and does not allow for integer operations. Any help on this matter would be appreciated.
