How can I print 3840×2160 photos as 4×6 prints without distortion?

I have photos from a phone with a resolution of 3840×2160 pixels. I want to print them at 102×152 mm (4×6 inches), but online printing services either crop the image or leave white borders at the top and bottom. If I resize to fill the print, the image becomes stretched.
Is there any way to make a 3840×2160 image fit a 4×6 print exactly without cropping, borders, or distortion? If not, what are the practical options?

Strange question...
You don't want to crop, you don't want borders, you don't want to stretch the image...but you want to somehow put one rectangle into another rectangle of a different aspect ratio.
Those are the only options. What other options could there be?
It's like putting a round peg in a square hole. Well, a rectangular peg in a rectangular hole. This isn't specific to photography - it's just geometry.

No. A 3840×2160 image is 16:9 aspect ratio, while a 4×6 print is 3:2. Because the shapes are different, you cannot fill a 4×6 print exactly without one of these trade-offs:
- crop part of the image
- leave white borders
- stretch/distort the image
- print at a different size that matches 16:9
So the printing service is behaving normally.
If you want a true 4×6 print, the usual solution is to crop the photo to 3:2 before ordering. For 3840×2160, that means trimming the width to about 3240×2160 (or equivalently trimming top/bottom if you rotate the image).
If you do not want to lose any of the image, keep the full 16:9 frame and accept borders, or choose a print size closer to 16:9 instead of 4×6.
Any image editor can do the crop, including Photoshop, GIMP, Lightroom, Darktable, IrfanView, or similar tools.
