Is there any way to run 3rd party application on C9300 from bootflash?

[Tohru Ohzono]

I believe only Cisco-signed applications can be hosted on the bootflash.
Is there any way to sign 3rd party application?
Or is a USB SSD storage mandatory for them?

[Restrictions for Application Hosting]
> In Cisco IOS XE Amsterdam 17.3.3 and later releases, application hosting is enabled on the bootflash, however, only Cisco-signed applications are hosted.

Not sure from docker it could be possible. Came across this repo for related information -https://github.com/jeremycohoe/c9k-wireshark
