You should be able to call anything using send. For typescript you might have to cast it to an Array, but there is probably also a positional equivalent? Do you have a link to the API?

It's actually custom for geth, and I guess few more backends like Ergion have similar API https://www.quicknode.com/docs/ethereum/debug_traceTransaction

However Openetheruem has different API https://openethereum.github.io/JSONRPC-trace-module#trace_replaytransaction

The debug API is not presently a standard that is implemented the same way across various backends (geth, openethereum, ...). Hence it's not present on the JsonRpcProvider yet.

If you are looking for an API that formats the response for you along with types, instead of returning the raw rpc response, you may extend the provider and implement the formatting.

class GethRpcProvider extends StaticJsonRpcProvider {
    async debugTraceTranscation(txHash: string) {
        // implement formatting logic once
    }
}
