Is it possible to log ship from on-premise SQL server to Azure SQL Managed Instance? From the docs, it would seem that restoring a full database backup file is possible, but can one also restore transaction logs?

(the idea is to minimize downtime in a migration from on-prem to MI).

Thanks.
No, log shipping to Managed Instance is not possible; it only supports the restore of full backups. See this thread:

Lesson Learned #82: Azure SQL Database Managed Instance supports only COPY_ONLY restoring a database backup (was here before)

And the limited syntax diagram for RESTORE in the documentation for Managed Instance:

RESTORE Statements (Transact-SQL)

The docs imply that RESTORE ... FROM URL will implicitly add WITH RECOVERY and so there will be no opportunity for logs to be applied after the initial restore. So your downtime will be &gt;= the time it takes to take a COPY_ONLY full backup, put it somewhere MI can access, restore it, and re-point your app(s).
