There is a note in the documentation that the following properties cannot be updated by an app with only application permissions:

aboutMe, birthday, employeeHireDate, interests, mySite, pastProjects, preferredName, responsibilities, schools, and skills.

Which is exactly your case because you've added only application permissions to your app in Azure.

Update

Another limitation can be that User is a composite type and some properties are covered by different services and Graph API doesn't support updates across multiple services.

According this User object in Azure AD has the following properties:

accountEnabled, ageGroup, assignedLicenses, assignedPlans, assignedPlans, assignedPlans, businessPhones, city, companyName, consentProvidedForMinor, country, createdDateTime, createdObjects, creationType, department, displayName, employeeHireDate, employeeId, employeeOrgData, employeeOrgData, employeeType, externalUserState, faxNumber, givenName, identities, imAddresses, isResourceAccount, jobTitle, mail, mailNickname, manager, mobilePhone, officeLocation, onPremisesExtensionAttributes, onPremisesImmutableId, onPremisesLastSyncDateTime, onPremisesProvisioningErrors, onPremisesProvisioningErrors, onPremisesSamAccountName, onPremisesSecurityIdentifier, onPremisesSyncEnabled, otherMails, passwordPolicies, passwordProfile, postalCode, preferredLanguage, provisionedPlans, ,provisionedPlans proxyAddresses, showInAddressList, state, streetAddress, surname, usageLocation, userPrincipalName, userType

When updating User, those properties cannot be updated together with Sharepoint Online properties.

aboutMe, birthday, hireDate, interests, mySite, pastProjects, preferredName, responsibilities, schools, skills
