I managed to start uploading large files by using multer and callHanlder:
@/server/api/upload.ts

import { CompatibilityEvent, callHandler } from 'h3';
import multer from 'multer';

const storage = multer.diskStorage({
	destination: (req, file, cb) => {
		cb(null, './');
	},
	filename: (req, file, cb) => {
		cb(null, file.originalname);
	},
});

export default async (event: CompatibilityEvent): Promise<IServerResponse> => {
	await callHandler(multer({ storage }).single('file'), event.req, event.res);
	return { success: true };
};

It turns out all this time it worked just Typescript complains about types:

text:

An argument of type "RequestHandler<ParamsDictionary, any, any, ParsedQs, Record<string, any>>" cannot be assigned to a parameter of type "Middleware".
   Parameter types "req" and "req" are incompatible.
     The 'IncomingMessage' type is missing the following properties from the 'Request<ParamsDictionary, any, any, ParsedQs, Record<string, any>>' type: get, header, accepts, acceptsCharsets and 25.ts(2345) more
