Sure. No need for --(experimental)-strip-types since I-forget-which-version, but I use Node.js 24.17 here.

  // ---- dev-ts-resolve.js
  export async function resolve(specifier, context, nextResolve) {
    try {
      return await nextResolve(specifier, context);
    } catch (err) {
      const isRelative = specifier.startsWith('./')
        || specifier.startsWith('../')
        || specifier.startsWith('/')
        || specifier.startsWith('file:');
      if (err?.code === 'ERR_MODULE_NOT_FOUND' && isRelative && specifier.endsWith('.js')) {
        return nextResolve(`${specifier.slice(0, -3)}.ts`, context);
      }
  
      throw err;
    }
  }
  // ---- dev-loader.js
  import { register } from 'node:module';
  
  register('./dev-ts-resolve.js', import.meta.url);
  // ----

usage:

  node --import ./dev-loader.js --watch-path=./src
