Is it possible to export an image from Google Earth Engine as ASCII raster
Export.image.toDrive({ image: 'image', region: region, scale: 30, crs: 'EPSG:4326', });

No it is not. Currently the only supported output formats are GeoTIFF and TFRecord. https://developers.google.com/earth-engine/apidocs/export-image-todrive

Just to add, TIFF to ASCII can be easily done using QGIS: https://wiki.tuflow.com/index.php?title=QGIS_Export_Raster_to_asc – CrossLord Aug 17 '21 at 07:52

Not very efficient, you can sample the pixels and export them to CSV.
// Define Region of interest
var roi = ee.Geometry.Polygon(
[[[11.304653628407992, 42.60010798357459],
[11.304653628407992, 42.40673200589496],
[11.605404360829867, 42.40673200589496],
[11.605404360829867, 42.60010798357459]]], null, false);
// get L8 image
var l8 = ee.ImageCollection("LANDSAT/LC08/C01/T1_TOA")
.filterBounds(roi).filterMetadata('CLOUD_COVER','less_than',5).first()
// add Lat/Lon
var ll = ee.Image.pixelLonLat()
var proj = l8.select('B1').projection()
var image = l8.addBands(ll.reproject(proj)).clip(roi)
// sample the image
var p = image.sample({region:roi, scale:30, projection:proj})
// Display
Map.addLayer(image)
// Export to CSV file
Export.table.toDrive({collection:p, description:'points', fileFormat:'CSV'})
